What is the molar mass in grams of 1.24 moles of beryllium?
1,24 moles of beryllium is equal to 11,175 g.
How many grams are in 0.02 moles of beryllium iodide BeI2?
To find the mass in grams of 0.02 moles of beryllium iodide (BeI₂), we first calculate its molar mass. The molar mass of beryllium (Be) is approximately 9.01 g/mol, and iodine (I) is about 126.90 g/mol. Thus, the molar mass of BeI₂ is 9.01 + (2 × 126.90) = 262.81 g/mol. Therefore, 0.02 moles of BeI₂ would weigh approximately 0.02 × 262.81 = 5.26 grams.
What is the percent composition of beryllium in Be and oxide O?
The percent composition of beryllium (Be) in beryllium oxide (BeO) can be calculated using the molar masses of the elements. The molar mass of Be is approximately 9.01 g/mol, and that of oxygen (O) is about 16.00 g/mol, giving BeO a total molar mass of roughly 25.01 g/mol. The percent composition of beryllium in BeO is then calculated as (9.01 g/mol / 25.01 g/mol) × 100%, which is approximately 36.04%.
If the molar mass of Li2C1O3 is 73.8 gramsmole what's the molecular formula?
The molecular formula for lithium chlorate is Li₂ClO₃, which consists of two lithium (Li) atoms, one chlorine (Cl) atom, and three oxygen (O) atoms. Given the molar mass of 73.8 grams/mole, this is consistent with the calculated molar mass of Li₂ClO₃, which is approximately 73.89 grams/mole. Thus, the molecular formula is indeed Li₂ClO₃.
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 mass of potassium chlorate would contain 40.0g of oxygen?
To calculate the mass of potassium chlorate containing 40.0g of oxygen, first determine the molar mass of oxygen (16g/mol). Then, use the molecular formula of potassium chlorate (KClO3) to find the oxygen's molar ratio in KClO3 (1:3). Finally, calculate the mass of KClO3 using the molar mass and the molar ratio to find that approximately 186 grams of potassium chlorate contain 40.0g of oxygen.
How do you find the molar mass of beryllium oxide?
To find the molar mass of beryllium oxide (BeO), you will need to determine the individual molar masses of beryllium (Be) and oxygen (O) from the periodic table and then add them together. The molar mass of Be is about 9 g/mol and the molar mass of O is about 16 g/mol. When you add them together, you'll find that the molar mass of BeO is approximately 25 g/mol.

First calculate the molar mass of the potassium chlorate KClO3 K is 39.1, Cl is 35.45 and O is 16 x 3 =48 The molar mass for one mol is 122.55g/mol The percent composition is the part the oxygen contributed divided by the total molar mass times 100(to convert a decimal to a percent) 48/122.55 x 100 is 39.167% Potassium Chlorate is 39.167 percent oxygen
How many grams are in 0.02 moles of beryllium iodide BeI2?
To find the mass in grams of 0.02 moles of beryllium iodide (BeI₂), we first calculate its molar mass. The molar mass of beryllium (Be) is approximately 9.01 g/mol, and iodine (I) is about 126.90 g/mol. Thus, the molar mass of BeI₂ is 9.01 + (2 × 126.90) = 262.81 g/mol. Therefore, 0.02 moles of BeI₂ would weigh approximately 0.02 × 262.81 = 5.26 grams.
What is the percent composition of beryllium in Be and oxide O?
The percent composition of beryllium (Be) in beryllium oxide (BeO) can be calculated using the molar masses of the elements. The molar mass of Be is approximately 9.01 g/mol, and that of oxygen (O) is about 16.00 g/mol, giving BeO a total molar mass of roughly 25.01 g/mol. The percent composition of beryllium in BeO is then calculated as (9.01 g/mol / 25.01 g/mol) × 100%, which is approximately 36.04%.
How many grams of potassium chlorate decomposes to yield 30 grams of oxygen?
The molar mass of potassium chlorate (KClO3) is 122.55 g/mol. This means that 122.55 grams of potassium chlorate yield 3 moles of oxygen gas. To calculate the amount of potassium chlorate that decomposes to yield 30 grams of oxygen, you can set up a simple ratio using the molar masses.
