Questions and answers

What is the formula n/m m?

What is the formula n/m m?

n = m/M n is the amount of substance, in moles, mol. m is the mass of the substance, in grams, g. M is the molar mass of the substance (the mass of one mole of the substance) in g mol-1.

How do you calculate concentration in mM?

Calculate concentration in millimolars using the formula: Molarity (millimolars)= Amount (in millimoles)/Volume of solution (in liters). In our example, the volume of the solution is 500 ml or 0.5 liters. The molarity of NaOH would be: Molarity (NaOH)= 12.5 millimoles/0.5 liters=25 millimolars.

What is nM concentration?

A nanomolar (nM) is the decimal fraction of a molar, which is the common non-SI unit of molar concentration. For example, a 2-molar (2 M) solution contains 2 moles of a certain substance in one liter of a liquid or gaseous mixture. A molar (M) is the common non-SI unit of molar concentration.

How do you calculate the density?

The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

How do you convert nm to N Mm?

N.m↔ 1 N.m = 1000

How do you use nm MM?

There is an equation that describes moles in relation to the mass of a substance and it’s molar mass, it is n=m/MM (the number of moles equals to mass of the sample divided by its molar mass).

How do you convert Millimolar to grams?

How do you convert millimoles into grams? This is the weight in grams of 1 mole of the compound. 1 millimole Fe2O3 = 159.69 / 1000 = 0.1597 grams = 159.69 milligrams.

What is Millimolar concentration?

Concentrations in molarities are given by expressing the number of moles of the. substance present in a defined volume of solution: A 1 molar (1 M) solution contains 1 mole per litre (1 mol/l) a 1 millimolar (1 mM) solution contains 1 millimole per litre (1 mmol/l)

How do you find concentration in nM?

From the attachment, the concentration you seek is actually clearly stated. Your order contains 2.98 x 10-10 M of content. This concentration is equal to 2.98 x 10-7 mM = 2.98 x 10-1 nM. The molar concentration was obtained from the wt concentration and molar mass; Molar concentration = wt concentration / Molar mass.

How do you convert nM to UG mL?

The simple formula is: ( µg/mL ) = ( µM ) * ( MW in KD) , ( ng/mL ) = ( nM ) * ( MW in KD) , ( pg/mL ) = ( pM ) * ( MW in KD) .

Which is the correct formula for density, m or V?

p = density. m = mass. V = volume. The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V).

How do you calculate the density of a gas?

To find the density of the gas, you need to know the mass of the gas and the volume. First, find the volume. Here is the ideal gas law equation rearranged to solve for V: V = nRT/P. After you have found the volume, you must find the mass.

How is the density of a material defined?

The density of a material, typically denoted using the Greek symbol ρ, is defined as its mass per unit volume.

What is the density of water in m³?

Water has a density of 1000kg/m³, therefore anything that floats in water has less density than that, and anything that sinks has a greater density (for example, cooking oil is around 920kg/m³; tin is 7310kg/m³; cork is 240kg/m³; and Aerogel, one of the least dense solids we know of, has a density of 1kg/m³).
