Answer :
To find out how many grams of nickel are in 1.57 moles of Ni, you can use the concept of molar mass. The molar mass of a substance tells you how many grams are in one mole of that substance.
Here’s a step-by-step breakdown to solve the question:
1. Identify the molar mass of nickel (Ni): We're given that the molar mass of nickel is 58.69 grams per mole (g/mol).
2. Identify the number of moles of nickel: The problem states that you have 1.57 moles of nickel.
3. Use the formula to calculate the mass in grams:
[tex]\[
\text{Mass in grams} = \text{Number of moles} \times \text{Molar mass}
\][/tex]
4. Substitute the given values into the formula:
[tex]\[
\text{Mass in grams} = 1.57 \, \text{moles} \times 58.69 \, \text{g/mol}
\][/tex]
5. Perform the multiplication:
[tex]\[
\text{Mass in grams} = 92.1433 \, \text{g}
\][/tex]
Therefore, there are approximately 92.1433 grams of nickel in 1.57 moles of Ni.
