Answer:
Explanation: English please
Hey there!
Molar mass CuSO4 = <span>159.609 g/mol
</span><span>Note that the molarity is in the enunciation of the issue, then the problem asks the mass of the solute :
Volume in liters of solution:
150 mL / 1000 => 0.15 L
</span><span>Calculation of quantity in Moles of the solute :
</span>
1 L ----------------- 0.300 M
0.15 L ------------ ( moles )
Moles CuSO4 = 0.15 * 0.300 / 1
Moles CuSO4 = 0.045 moles
Therefore :
1 mole CuSO4 --------------------- 159.609 g
0.045 moles CuSO4-------------- mass
mass = 0.045 * 159.609 / 1
mass = 7.182405 g of CuSO4
