Question

find no of moles of 50g of CaCO2​

Answer 1

Answer:

Answer:3.011×1023.

Explanation:Given mass=50g.

Molar mass of Caco3 is =40+12+3×16=100.

Number of moles of Caco3 will be 50/100=0.5.

1 mol of Caco3 contains 6.022 ×1023 molecules.

Hence 0.5 mol of Caco3 molecules will contain.

0.5×6.022 ×10 23 which gives 3.011 ×10 23.

Answer 2

Explanation:

.

• Explanation:Given mass=50g.
• Molar mass of Caco3 is =40+12+3×16=100.
• Number of moles of Caco3 will be 50/100=$0.5$

• 1 mol of Caco3 contains 6.022 ×1023 molecules.
• Hence 0.5 mol of Caco3 molecules will contain.
• 0.5×6.022 ×10 23 which gives 3.011 ×10 23.
