Question

calculate the mass, in grams, of 0.695 moles of mn. the mass of one mole of mn is 54.94 g.

Explanation:

Step1: Recall the formula for mass from moles

The formula to calculate mass (in grams) from moles is \( \text{Mass} = \text{Moles} \times \text{Molar Mass} \). Here, moles of Mn is \( 0.695 \) mol and molar mass of Mn is \( 54.94 \) g/mol.

Step2: Substitute the values into the formula

Substitute \( \text{Moles} = 0.695 \) and \( \text{Molar Mass} = 54.94 \) into the formula: \( \text{Mass} = 0.695 \, \text{mol} \times 54.94 \, \text{g/mol} \).
Calculate the product: \( 0.695 \times 54.94 \approx 38.18 \).

Answer:

The mass of \( 0.695 \) moles of Mn is approximately \( 38.18 \) grams.
