Convert molecules of vitamin d (molar mass 384.7 g/mol) to grams of vitamin d.

Chemistry
1 answer:
velikii [3]2 years ago
3 0

The 6.023 * 10²³  molecule means  384.7 grams of Vitamin D.

<h3>What is a mole ?</h3>

A mole is a universal unit used to measure large number of atoms , molecules of an element.

one mole is equal to the Avogadro's Constant.

Mole is equal to the ratio of the mass of a compound to its molecular weight

It is given that Vitamin D is present

no. of molecule = 6.023 * 10²³

6.023 * 10²³ molecule constitutes of 1 mol

1 mole  is equal to the molar mass of a compound/ element

Therefore 1 mole = 384.7grams of Vitamin D

and hence 6.023 * 10²³  molecule means 384.7 grams of Vitamin D.

What's the formula mass for (NH4)3PO4
maria [59]
The formula mass of a molecule is the sum of the atomic weights of the atoms in the empirical formula of the compound. It is also known as Formula Weight.
The atomic weights of
N = 14.01 amu
H = 1.00 amu
P = 30.97 amu
O = 16.0 amu

Now, we will calculate now the formula mass of a given substance
3(14.01) + 12(1.00) + 1(30.97) + 4(16.0) = 42.03 + 12.00 + 30.97 + 64.0 = 149.0 amu

Therefore, the formula mass for (NH4)3PO4 is 149.0 amu

A chromatogram has three bands with Rf values of 0.25, 0.47 and 0.82 which value corresponds to the material with the highest mo
S_A_V [24]

The compound that has the highest molecular weight based on the chromatogram is the compound with Rf 0.25.

A chromatogram is an output that shows the extent of separation of the components of a mixture. If the Rf is high, then it means that the substance traveled a large distance through the plate and vice versa.

Similarly, the molecular mass of the substances correlate with the Rf value observed for each component. The components with high molecular mass always show a low Rf value.

This implies that the lowest Rf value corresponds to the largest relative molecular mass. Thus, the compound that has the highest molecular weight based on the chromatogram is the compound with Rf 0.25.
