Answer 1

Answer:

0.55

Explanation:

Answer 2

Given: Given quantity is $1.2×10^{24}$ molecules of CO.

To find: We have to find the mass.

Solution:

To determine the mass we have to follow the below steps-

The given compound is CO.

C has an atomic mass of 12 and Oxygen has an atomic mass of 16.

Thus the molecular mass of CO is 12+16=28 grams.

Thus we can write, $6.023×10^{23}$ number of molecules have 28 grams of CO.

$1.2×10^{24}$ number of molecules of CO will have-

$\frac{1.2 \times {10}^{24} \times 28 }{6 \times {10}^{23} } \\ = 0.2 \times 10 \times 28 \\ = 56$

The result is 56.

$1.2×10^{24}$ molecules of CO has 56 grams.
