Question

Calculate i) Number of moles of Carbon in 60 g of Carbon

ii) Number of atoms of Nitrogen in 7 g of Nitrogen

iii) Number of NaCl molecules in 58.5 g of NaCl.

(C = 12, N= 14, Na = 23, Cl = 35.5 ) if anyone please I will give you the tag of best answer ​

Answer 1

Answer:

i)given mass of carbon =60g of carbon

molar mass of carbon=12g

moles=?

Formula to be used;

No.of moles = given weight /molar mass

60/12

=5 moles

Therefore, 5 moles of carbon are present in 60g of carbon
