32.7 g x 1 mol/22.99 g = 1.422 mol x 6.022x10^23 molecules/1mol = 8.565 x 10^23 molecules(also called atoms)

How many moles of Na are in 42 grams of Na?

To find the number of moles of Na in 42 grams, we can use the molar mass of Na, which is approximately 23 grams/mol. First, calculate the number of moles by dividing the given mass by the molar mass: 42 grams / 23 grams/mol = 1.83 moles of Na.


How many moles are in 4.99 g of Na?

0.21705 moles. There are 22.9898 grams sodium in 1 mole.


How many moles of hydrogen gas will be produced if 25g of Na reacts completely with excess HCl?

Using the equation 2Na + 2HCl -> 2NaCl + H2, we can see that 2 moles of Na react with 2 moles of HCl to produce 1 mole of H2. Calculate moles of Na: 25g Na * 1 mol Na / 23g Na = 1.09 mol Na. Since the reaction is with excess HCl, the number of moles of H2 produced will be half the number of moles of Na, so it will be 0.545 moles of H2.


How many moles of sodium oxide will be produced when 10 moles of sodium react with oxygen This is the formula for the reaction?

Balanced equation. 4Na + O2 -> 2Na2O 10 moles Na (2 moles Na2O/4 moles Na) = 5.0 moles Na2O produced


How many Na atoms are there in 0.125 moles of Na metal?

0.125 moles x 6.02x10^23 atoms/mole = 7.53x10^22 atoms


How many moles of Na Cl could be made by combining 20000 mole of Na with 2 moles of Cl?

2 moles of NaCl, of course. Cl would definitely limit in this one to one reaction and you would have 19998 moles Na in excess.


How many moles of Na are in 15 g of NaCl?

To find the number of moles of Na in 15 g of NaCl, you first need to calculate the molar mass of NaCl, which is 58.44 g/mol. Since Na makes up 39.34% of the molar mass of NaCl, you can calculate the moles of Na as (15 g / 58.44 g/mol) * 0.3934 = 0.255 moles of Na.


How many moles of Na are needed to make 4 moles of H2?

It depends on what you are reacting the sodium with to generate hydrogen gas. The question is incomplete and cannot be answered as it is written


If 250ml of solution contains 42g of Magnesium nitrate calculate the concentration of nitrate ions?

To calculate the concentration of nitrate ions, we first need to find the molar mass of Mg(NO3)2, which is approximately 148.33 g/mol. Next, we calculate the number of moles of Mg(NO3)2 in 42g, which is 42g/148.33 g/mol = 0.283 moles. Since there are 2 nitrate ions per Mg(NO3)2, the number of moles of nitrate ions is 0.283 moles x 2 = 0.566 moles. Finally, we divide the moles of nitrate ions by the volume of solution in liters (0.25 L) to get the concentration: 0.566 moles / 0.25 L = 2.26 M.
