Answer :
To find out how many moles are present in 1.64 g of [tex]\( MgSO_4 \)[/tex], we need to use the formula for moles:
[tex]\[
\text{moles} = \frac{\text{mass}}{\text{molar mass}}
\][/tex]
Here are the steps to solve this problem:
1. Determine the mass of [tex]\( MgSO_4 \)[/tex] given:
You have 1.64 grams of [tex]\( MgSO_4 \)[/tex].
2. Find the molar mass of [tex]\( MgSO_4 \)[/tex]:
The molar mass of [tex]\( MgSO_4 \)[/tex] is approximately 120.366 g/mol.
3. Calculate the number of moles:
Use the formula to divide the given mass by the molar mass:
[tex]\[
\text{moles of } MgSO_4 = \frac{1.64 \text{ g}}{120.366 \text{ g/mol}}
\][/tex]
4. Perform the division:
After performing the division, we find that there are approximately 0.0136 moles of [tex]\( MgSO_4 \)[/tex].
Hence, the number of moles present in 1.64 g of [tex]\( MgSO_4 \)[/tex] is approximately 0.0136 mol.
[tex]\[
\text{moles} = \frac{\text{mass}}{\text{molar mass}}
\][/tex]
