What is the weight in grams of 3.36 x 10^23 molecules of copper sulfate
Llana [10]

Answer:

m=89.0g

Explanation:

Hello!

In this case, since we are given the formula units (molecules) of copper sulfate, it is possible to compute the moles of this compound via the Avogadro's number:

n=3.36x10^{23}molecules*\frac{1mol}{6.022x10^{23}molecules}\\\\n=0.558mol

Now, given the molar mass of copper sulfate which is 159.60 g/mol, the required mass in grams turns out:

m=0.558mol*\frac{159.60g}{1mol}\\\\m=89.0g

Best regards!

Show a numerical setup for calculating the number of moles in the sample of CaCO3
Delvig [45]

The numerical setup is

<span>11<span>g</span></span>CO2×1 mol CO2/44.01g CO2=0.25 mol CO2

gCO2 cancels out so it is

11 x 1 mol CO2/44.1 CO2= 0.25 mol CO2
