To calculate the percentage of mass lost for bicarbonates, you would first determine the initial mass of the bicarbonate compound. Then, subtract the final mass after the reaction or process from the initial mass to find the mass lost. Finally, divide the mass lost by the initial mass and multiply by 100 to get the percentage of mass lost.

How do you calculate the percentage of water in a hydrate?
To calculate the percentage of water in a hydrate, you first determine the molar mass of the water and the compound. Then, you divide the molar mass of the water by the molar mass of the hydrate and multiply by 100 to get the percentage.
An unknown hydrate ac xH2O has a mass of 1.632 g and the anhydrous compound AC has a mass of 1.008 g What is the experimental percentage of water in the hydrate?
To find the experimental percentage of water in the hydrate, we need to calculate the mass of water lost during dehydration. Mass of water lost = 1.632 g - 1.008 g = 0.624 g Experimental percentage of water = (mass of water lost / initial mass of hydrate) x 100% = (0.624 g / 1.632 g) x 100% ≈ 38.24%
How do you calculate the percentage of a substance in a mixture?
To calculate the percentage of a substance in a mixture, you take the mass of the substance you are interested in and divide it by the total mass of the mixture. Then, multiply the result by 100 to get the percentage.
How do you calculate the percent by mass of an element in a compound?

What is the percentage mass of oxygen in morphine?
The chemical formula for morphine is C17H19NO3. To calculate the percentage mass of oxygen in morphine, determine the molar mass of oxygen in the formula (3(16 g/mol)) and divide by the molar mass of morphine (285 g/mol), then multiply by 100 to get the percentage. The percentage mass of oxygen in morphine is approximately 16.8%.
HOW DO I CALCULATE THE PERCENTAGE BY MASS OF ETHANOL IN A MIXTURE?
First, determine the mass of ethanol in the mixture by dividing the mass of ethanol by the total mass of the mixture. Then, multiply the result by 100 to get the percentage by mass of ethanol in the mixture. For example, if a mixture contains 20g of ethanol in a total mass of 100g, the percentage by mass of ethanol would be (20g / 100g) * 100 = 20%.
What is the mass percentage of strontium in strontium sulfide?
To calculate the mass percentage of strontium in strontium sulfide, you need to know the molar mass of strontium sulfide (SrS), which is 119.63 g/mol. The molar mass of strontium (Sr) is 87.62 g/mol. To find the mass percentage, you would divide the molar mass of strontium by the molar mass of strontium sulfide, and then multiply by 100. This would give you the mass percentage of strontium in strontium sulfide, which is approximately 73.2%.
