The density is 5.4 g/mL and the volume is 12.9 mL.
marishachu [46]

Answer:

69.66 g

Explanation:

We have the following from the question;

Density of the substance = 5.4 g/ml

Volume of substance = 12.9 ml

Mass of substance= the unknown

Since we have both density and volume of the substance, the question must be for us to obtain the mass of the substance, hence;

Density= mass/volume

Mass= Density × volume

Mass = 5.4 g/ml × 12.9 ml

Mass= 69.66 g

How many molecules are in 6.0g of sodium phosphate?
Phantasy [73]

Answer:

2.2 x 10²² molecules.

Explanation:

  • Firstly, we need to calculate the no. of moles in (6.0 g) sodium phosphate:

<em>no. of moles = mass/molar mass </em>= (6.0 g)/(163.94 g/mol) = <em>0.0366 mol.</em>

  • <em>It is known that every mole of a molecule contains Avogadro's number (6.022 x 10²³) of molecules.</em>

<em />

<u><em>using cross multiplication:</em></u>

1.0 mole of sodium phosphate contains → 6.022 x 10²³ molecules.

0.0366 mole of sodium phosphate contains → ??? molecules.

<em>∴ The no. of molecules in  6.0 g of sodium phosphate</em> = (6.022 x 10²³ molecules)(0.0366 mole)/(1.0 mole) = <em>2.2 x 10²² molecules.</em>
