Question

How many grams of calcium cyanide (ca(cn)2) are contained in 0.69 mol of calcium cyanide?

Answer 1

63.55783199999777 grams

Answer 2

Step-by-step explanation:

As number of moles is equal to mass divided by molar mass. As molar mass of calcium cyanide is 92.11 g/mol.

So, calculate the mass of calcium cyanide as follows.

No. moles of calcium cyanide =
`\frac{mass}{\text{molar mass}}`

0.69 mol =
`(mass)/(92.11 g/mol)`

mass = 63.55 g

Thus, we can conclude that mass of calcium cyanide is 63.55 g.
