how would you classify a solution that contains 1.5g of lithium carbonate in 100g of water at 20 degrees
To classify the solution that contains 1.5g of lithium carbonate in 100g of water at 20 degrees, you can look at its concentration. The concentration of a solution tells you how much solute is dissolved in a given amount of solvent.
To calculate the concentration, you can use the formula:
Concentration = (mass of solute) / (mass of solvent)
In this case, the mass of solute is 1.5g (lithium carbonate) and the mass of solvent is 100g (water). Plugging these values into the formula, we get:
Concentration = 1.5g / 100g
Simplifying this, the concentration of the solution is:
Concentration = 0.015 (or 1.5%)
So, the solution can be classified as a 1.5% lithium carbonate solution in water at 20 degrees.
