Question

Convert into mole:16 g of oxygen gas (O2)36 g of water (H2O)22 g of carbon dioxide (CO2)

Answer 1

Explanation:

moles=given mass/molar mass Now calculate .

Answer 2

Answer:

For oxygen gas , water and carbon di-oxide No. of moles = 0.5 moles.

Explanation:

We know the formula for no. of moles = $\frac{given\ mass}{molar\ mass}$

For oxygen gas, given mass = 16 gm

So,

No. of moles = $\frac{16}{32}$ = 0.5 moles

For water, given mass = 36 gm

So,

No. of moles = $\frac{36}{18}$ =0.5 moles

For carbon dioxide, given mass = 22 gm

So,

No. of moles = $\frac{22}{44}$ = 0.5 moles

For oxygen gas , water and carbon di-oxide No. of moles = 0.5 moles.
