number of mole in 850.5g of zinc
Well, let me calculate that for you. Just give me a moment while I put on my Mole-tex gloves and fire up the calculator. *beep boop beep*
The molar mass of zinc (Zn) is approximately 65.38 g/mol. So, to find the number of moles, we divide the given mass of zinc (850.5g) by the molar mass of zinc:
850.5g / 65.38 g/mol = 13.01 moles (approximately)
So, according to my calculations, there are about 13.01 moles of zinc in 850.5g. That's a whole lot of moles! I hope they don't start a revolution or anything. Keep an eye out just in case!
To determine the number of moles in 850.5g of zinc, you need to use the molar mass of zinc.
The molar mass of zinc (Zn) is 65.38 g/mol. This means that in one mole of zinc, there is 65.38 grams.
To find the number of moles in 850.5g of zinc, you can use the following formula:
Number of moles = (Mass of substance in grams) / (Molar mass of substance)
Plugging in the values:
Number of moles = 850.5g / 65.38 g/mol
Number of moles = 13.01 moles
Therefore, there are approximately 13.01 moles of zinc in 850.5g.
To find the number of moles in a given mass of a substance, you need to use the molar mass of that substance. In this case, you want to find the number of moles in 850.5g of zinc.
Step 1: Find the molar mass of zinc (Zn)
The atomic mass of zinc is found on the periodic table, which is 65.38 g/mol.
Step 2: Calculate the moles of zinc
To calculate the moles, divide the given mass (850.5g) by the molar mass of zinc (65.38 g/mol):
850.5g / 65.38 g/mol = 13.0156 mol
Step 3: Round off the answer
Since the number of moles has more decimal places than are typically significant, you can round off the answer to an appropriate number of decimal places. In this case, you can round off to three decimal places:
13.0156 mol ≈ 13.016 mol
So, there are approximately 13.016 moles of zinc in 850.5g.
Find the molar mass for zinc (=M g/mole)
Number of moles = 850.5 g / M g/mole
