if 3.60g of NaCl is dissolved into 75.00mL of water, what is the concentration of this salt solution, in m/v%?
Wouldn't that be 3.60 x (100/75) = ?
3.60 *(100/75)
To find the concentration of a salt solution in m/v% (mass/volume percent), we need to calculate the ratio of the mass of the solute (NaCl) to the volume of the solution (water).
First, convert the given volume of water from milliliters (mL) to liters (L):
75.00 mL ÷ 1000 = 0.075 L
Next, calculate the concentration by dividing the mass of the solute by the volume of the solution and then multiplying by 100 to obtain the percentage:
Concentration (m/v%) = (mass of NaCl / volume of solution) * 100
The mass of NaCl is given as 3.60 g. Thus, the concentration is:
Concentration (m/v%) = (3.60 g / 0.075 L) * 100
Concentration (m/v%) ≈ 48%
Therefore, the concentration of this salt solution is approximately 48% m/v.
