A hydrate is found to have the following percent composition 48.8 percent MgSO4 and 51.2 percent H2O What is the formula and name for this hydrate?
Alright... I assume ur asking this because its a hydrate so its easy peasy but because I don;t have a calculator or Periodic Table you do the math :P
FIrst find the molar mass of water and MgSO4
Then assume you have 100g of of sample... This means the mass of MgSO4 in the compound is 48.8g and the mass of H20 in the 100g sample would be 51.2g
Next, find the number of moles of MgSO4 and H2O by dividing the masses in the sample by their molar masses...
Next, divide the component with the larger number of moles by the component with the smaller number... THis gives you a ratio of how many more times of the more abundant material there is... eg) if there are more moles of H20 than MgSO4 and # mol H20/ #mol MgSO4 = 3/2, the ratio would be 2(MgSO4):3H2O
Use the ratio to fill in the formula and TADA!!

How can one determine the chemical formula from percent composition?
To determine the chemical formula from percent composition, you need to convert the percent composition of each element into moles. Then, divide the moles of each element by the smallest number of moles to find the ratio of elements. Finally, use this ratio to write the chemical formula.
What is the percent composition of a compound with the empirical formula CO2?
The percent composition of a compound with the empirical formula CO2 is 27.3% carbon and 72.7% oxygen.
How do you calculate the percent water in a hydrate?
To calculate the percent water in a hydrate, you first determine the mass of water in the hydrate by subtracting the mass of the anhydrous compound from the mass of the hydrate. Then, divide the mass of water by the total mass of the hydrate and multiply by 100 to get the percentage.
Is it necessary to know the formula of a compound in order to calculate its percent composition?
YES.For one to know the percentage composition,the amount of moles of the reacting element must be considered using the compound. •Well you dont really have to know just the formula. You can eaither use the formula if its given or the molar mass if its given. i just recently did a test where i was given either the Molar mass or Formula name and i had to figure out the percent composition. so it depends on the info given.
How can one determine the empirical formula from percent composition?
To determine the empirical formula from percent composition, first convert the percentages to grams. Then divide the grams of each element by its molar mass to find the moles. Finally, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio, which represents the empirical formula.
What is the important of percent composition of water in the hydrate compounds?
The percent composition of water in hydrate compounds is important because it helps determine the ratio of water molecules to the other compound in the structure. This information is crucial for accurately calculating the chemical formula of the hydrate and understanding its properties such as solubility, stability, and reactivity. Additionally, knowing the percent composition of water can provide insights into the compound's structure and behavior during reactions.

Can you determine the molecular formula of a substance from its percent composition?
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
What is the formula of a hydrate that is 85.3 percent barium chloride and 14.7 percent water?
The formula of the hydrate is BaCl2•2H2O. The ratio of barium chloride to water is 1:2, so there are two moles of water for every mole of barium chloride in the compound.
What is the importance of percentage composition?
Percent composition can be used to calculate the percentage of an element/compound in a mixture. From the percent composition, you can also find the empirical formula. And from the empirical formula you can find the actual molecular weight.
