0.68 moles of calcium to calcium atoms

Oksanka [162]

$0.68 \: moles \: calcium \times \frac{6.02 \times {10}^{23} \: calcium \: atoms }{1 \: mole \: calcium} \\$

The (( mole calcium ))s are simplified so the answer is based on the number of calcium atoms.

$0.68 \times 6.02 \times {10}^{23} = 68 \times {10}^{ - 2} \times 602 \times {10}^{ - 2} \times {10}^{23} \\$

$= 68 \times 602 \times {10}^{ - 4} \times {10}^{23} = 40936 \times {10}^{19} \\$

$calcium \: atoms = 40936 \times {10}^{19} \\$
