How many molecules of HCO3 are in 4 moles of the substance?

1 answer:

8 0

This question is about Avogadro's number.

Avogadro's number is the number is 6.022 * 10^23.

That means that 1 mol of molecules is 6.022 * 10^23 molecules, so 4 moles is 4 * 6.022 * 10^23 molecules = 24.088 * 10^23 molecules = 2.4088 * 10^24 molecules.

Answer: 2.4088 * 10^24 molecules.

Determine the percentage composition (by mass) of oxygen in NH4NO3.

Brrunno [24]

Answer:

60%

Explanation:

M(NH4NO3) = 2*14 +4*1 +3*16 = 80 g/mol

M(3O) = 3*16 = 48 g/mol

(48/80) *100 % =60% oxygen by mass.
