Question

Convert 12g of oxygen into moles?​

Answer 1

Answer:

Thus, 12 g of oxygen=321×12=0. 375 moles.

Thus, 20 g of water=181×20=1. 111 moles.

Thus, 22 g of carbon dioxide =441×22=0. 5 moles.

Answer 2

Number of moles = Given Mass/ Molar Mass

In this, Given Mass = 12g

Molar Mass = mass of Oxygen x 2

= 16 x 2 = 32g/mol

By using the formula,

No. of moles = 12 / 32

= 0.375mol
