What is the relative formula mass of each of the following compounds of potassium dichromate?
The relative formula mass of potassium dichromate (K2Cr2O7) is calculated by adding the atomic masses of its individual elements. The atomic masses of potassium (K), chromium (Cr), and oxygen (O) are 39.1, 52, and 16 respectively. Therefore, the relative formula mass of potassium dichromate is 294.2 g/mol.
What is the relative formula mass of iodine?
The relative formula mass of iodine is 253.8 g/mol.
What is the percentage by mass of carbon in potassium carbonate?
The molar mass of potassium carbonate (K2CO3) is 138.21 g/mol. The molar mass of carbon in K2CO3 is 12.01 g/mol. To find the percentage by mass of carbon, divide the molar mass of carbon by the molar mass of potassium carbonate and multiply by 100. This gives a percentage of approximately 8.69%.
What is the relative formula mass of copper?
The relative atomic mass of copper is approximately 63.55. To calculate the relative formula mass of copper, you sum the atomic masses of its atoms, which in this case would just be the atomic mass of copper. Therefore, the relative formula mass of copper would be 63.55.
Determine both the formula mass and molar mass of ammonium carbonate?
The formula mass of ammonium carbonate (NH4)2CO3 is 96.09 g/mol. Since the formula contains two ammonium ions, the molar mass of ammonium carbonate is 96.09 g/mol * 2 = 192.18 g/mol.
