Answer :
To find out how many grams of nickel are in 1.57 moles of nickel, you can use the molar mass of nickel, which is [tex]\(58.69 \, \text{g/mol}\)[/tex].
Here's how to calculate it step by step:
1. Identify the Given Information:
- Molar mass of nickel (Ni) = [tex]\(58.69 \, \text{g/mol}\)[/tex]
- Amount of nickel in moles = [tex]\(1.57 \, \text{mol}\)[/tex]
2. Use the Formula to Calculate Mass:
The formula to find the mass in grams is:
[tex]\[
\text{mass (g)} = \text{moles} \times \text{molar mass (g/mol)}
\][/tex]
3. Substitute the Values:
[tex]\[
\text{mass (g)} = 1.57 \, \text{mol} \times 58.69 \, \text{g/mol}
\][/tex]
4. Calculate the Result:
[tex]\[
\text{mass (g)} = 92.1433 \, \text{g}
\][/tex]
Thus, there are [tex]\(92.1433 \, \text{grams}\)[/tex] of nickel in [tex]\(1.57 \, \text{moles}\)[/tex] of nickel.
