What is the correct molar mass for hydrogen cyanide?
Hydrogen cyanide, HCN, has a molar mass of 27.03g/mol.
What is the percent composition of carbon in beryllium cyanide?
To determine the percent composition of carbon in beryllium cyanide, first find the molar mass of beryllium cyanide, then calculate the molar mass contributed by carbon. Finally, divide the molar mass of carbon by the total molar mass of beryllium cyanide and multiply by 100 to get the percent composition.
What is the molar mass for anhydrous(without water) barium sulfate?
The molar mass for anhydrous barium sulfate (BaSO4) is 233.43 g/mol
What is the mass in grams of barium in a sample of barium phosphate that also contains 10.0g of oxygen?
To determine the mass of barium in barium phosphate, we need to know the molar ratio of barium to oxygen in the compound. If we assume a 1:3 ratio between barium and oxygen in barium phosphate (Ba3(PO4)2), we can calculate the molar mass of barium and oxygen in the compound. With this information, we can find the mass of barium in the sample by subtracting the mass of oxygen from the total mass.
What i the mlar mass of magnesium cyanide write the formula?
The formula for magnesium cyanide is Mg(CN)2. To find the molar mass, you would add the molar mass of one magnesium atom (24.305 g/mol), and two cyanide ions (26.02 g/mol each). Therefore, the molar mass of magnesium cyanide is 76.345 g/mol.
How many grams barium hydroxide?
get the volume of the chemical and the mass and divide the mass by it's volume
What is the molar mass for an ionic substance with a chemical formula of BaSO4?
The molar mass of BaSO4 (Barium sulfate) can be calculated by adding the molar mass of each element present in the formula: Ba (barium) has a molar mass of 137.33 g/mol, S (sulfur) has a molar mass of 32.06 g/mol, and O (oxygen) has a molar mass of 16.00 g/mol. Adding these together gives a molar mass of 137.33 + 32.06 + (4 * 16.00) = 233.37 g/mol for BaSO4.
What is the name of the compound with the formula BaCN2?
The compound with the formula BaCN2 is called barium cyanide. It is composed of barium ions (Ba2+) and cyanide ions (CN-).
What is the molar mass of barium sulfate?
233.43 g On A+ the answer's 233.4 =]
What is the molar mass for silver nitrate?
CaCl2 = MM(Ca) + 2*MM(Cl) = 40 + 35.5 * 2 =111
How many moles of barium are present in a sample having a mass of 22.3 grams?
To determine the number of moles present, we first need to find the molar mass of barium (Ba), which is approximately 137.33 g/mol. Next, we use the formula n = m/M, where n is the number of moles, m is the mass of the sample (22.3 grams), and M is the molar mass (137.33 g/mol). By substituting these values, we find that there are approximately 0.162 moles of barium in the sample.
How many moles contained in 14.2g of barium sulfate?
The molar mass of barium sulfate, BaSO4 is 233.4 Amount of BaSO4 = mass of sample / molar mass = 14.2/233.4 = 0.0608mol 0.0608 moles of BaSO4 are conained in a 14.2g pure sample.
