Guida verificata passo dopo passo1
Identify the given quantity: 1.70 moles of carbon-12 (C).
Recall the molar mass of carbon-12, which is 12.0 grams per mole. This means 1 mole of carbon-12 has a mass of 12.0 g.
Use the formula to find mass from moles: \(\text{mass} = \text{moles} \times \text{molar mass}\).
Substitute the known values into the formula: \(\text{mass} = 1.70\ \text{mol} \times 12.0\ \text{g/mol}\).
Multiply the values to find the mass in grams (do not calculate the final number here, just set up the expression).
