Calculate the mass of CaCO3 in a 100ml solution that contains 70% of CaCO3 and the density is 1.02g/ml at room temperature
100 mL * 1.02 g/mL * 0.7 = 71.4 g CaCO₃
To calculate the mass of CaCO3 in the solution, we need to use the formula:
Mass = Volume x Density x Percentage of CaCO3
Given:
Volume = 100 mL
Density = 1.02 g/mL
Percentage of CaCO3 = 70%
First, we need to convert the volume from milliliters (mL) to liters (L) as density is given in grams per liter (g/L).
Volume = 100 mL = 100/1000 L = 0.1 L
Using the formula mentioned above, we can calculate the mass as follows:
Mass = 0.1 L x 1.02 g/mL x 0.70
Mass = 0.0714 g
Therefore, the mass of CaCO3 in the 100 mL solution is approximately 0.0714 grams.
To calculate the mass of CaCO3 in a 100 ml solution, we can use the following steps:
Step 1: Calculate the volume of CaCO3 in the solution.
Volume of CaCO3 = 70% of 100 ml
Volume of CaCO3 = 0.7 * 100 ml
Volume of CaCO3 = 70 ml
Step 2: Convert the volume of CaCO3 to mass using density.
Mass of CaCO3 = Volume of CaCO3 * Density
Mass of CaCO3 = 70 ml * 1.02 g/ml
Mass of CaCO3 = 71.4 g
Therefore, the mass of CaCO3 in the 100 ml solution is 71.4 grams.
