What is the molar mass of nitrogen dioxide?
1 mol Na X (22.99 Na / mol Na) = 22.99 g Na1 mol N X (14.01 g N / mol N) = 14.01 g N3 mol O X (16.00 g O / mol O) = 48.00 g OMolar mass of NaNO3 = 85.00 g/mol
What is the mass in grams of 0.15 moles sodium?
Molar mass Na = 22.99g/mol0.15 mol Na = 0.15*22.99 = 3.45g
If 1.20 grams of sodium metal are reacted with 3.00 ml of water how many grams of NaOH will be produced?
First write balance equation 2Na + 2H2O --> 2NaOH + H2 molar mass Na = 22.99 g/mol molar mass H2O = 18.02 g/mol molar mass NaOH = 40.0 g/mol Determine limiting reagent. 1.20 g Na * 1mol Na/22.99g Na = 0.05219 (0.0522) mol Na Since 2Na = 2NaOH in balanced equation, The mol of NaOH is also 0.0522 3ml h20 = 3 gram h20 (1ml^3=1g^3) 3g H20 * 1mol/18gH20 = 0.167 (0.17) mol H20 So .17 ml H20 equals .17 mol NaOH and .0522 mole Na equals .0522 mol NaOH The smaller one is the limiting reagent, which in this case is Na 0.0522mol NaOH*40g NaOH/1mol NaOH = 2.09 gram NaOH
How many grams of sodium does a 5.35 g sample of sodium bromide contain?
All you really need here is a ratio of molar masses, ie molar mass of Na/molar mass of NaBr So look at your periodic table and is says: Na = 23g/mol Br = 80g/mol therefore NaBr = 103g/mol so from this, you actually know a percentage of Sodium to Bromine, correct me if I'm wrong, someone else please but just take: (23g/mol)/103g/mol = 22.3% of you NaBr is actually Na, so take 5.35g * 0.223 and you get: 1.19g of Na in your NaBr Hope that helps. Cheers
How many ions are in 0.187 mol of na plus ions?
An Na(+) ion is just one electron short of a neutral atom. Electrons have a mass of 9.109 X 10^-31 Kilograms. Let us ignore that. 0.187 mol Na(+) (6.022 X 10^23/1mol Na(+) = 1.13 X 10^22 ions of Na(+)
What is the mass in grams of 0.0135 mole of the element Na?
molar mass Na = 22.99g/mol (atomic weight in grams) 0.0135mol Na x (22.99g/mol) = 0.310g Na
What is the mass of NaNO3?
1 mol Na X (22.99 Na / mol Na) = 22.99 g Na1 mol N X (14.01 g N / mol N) = 14.01 g N3 mol O X (16.00 g O / mol O) = 48.00 g OMolar mass of NaNO3 = 85.00 g/mol
What is the molar mass of nitrogen dioxide?
1 mol Na X (22.99 Na / mol Na) = 22.99 g Na1 mol N X (14.01 g N / mol N) = 14.01 g N3 mol O X (16.00 g O / mol O) = 48.00 g OMolar mass of NaNO3 = 85.00 g/mol
What is the mass of 9 moles of sodium?
1 mole Na = 22.989770g 9 mol Na x 22.989770g/mol = 206.9g Na = 200g Na rounded to one significant figure
How many atoms are in 14.500g Cr?
Use this fomula: (m/M)*NA in which m is mass in gram (g), M is molar mass (g/mol) and NA is the Avogadro number (mol^-1)
What is the mass in grams of 0.15 moles sodium?
Molar mass Na = 22.99g/mol0.15 mol Na = 0.15*22.99 = 3.45g
How many grams of NaCl would you have if you had 3.7 moles of NaCl?
Molar mass of Na = 22.9898g/mol Molar mass of Cl = 35.45g/mol Total molar mass = 58.4398g/mol 58.4398g * 3.7mol =216.22726g
What is the mass percentage of each element in the compound sodium hydroxide?
Molar mass Na: 23 g/mol O : 16 g/mol H : 1 g/mol Total NaOH: 40 g/mol Mass percentage %Na: 23/40 = 57.5% %O : 16/40 = 40% %H : 1 /40 = 2.5%
The number of grams in 0.350 mole of Na is?
1 mol of Na+ = 22.989g Na+(0.350 mol) x (22.989 g/mol) = 8.05 g Na+
What is the formula mass for NaClO?
22.9 + 35.3 + 15.9 = 74.1 g/mol Na: 22.9 g/mol Cl: 35.3 g/mol O: 15.9 g/mol
What is the mass number and atomic number of sodium?
Sodium (Na) has atomic number 11 and Atomic Mass of 22.99 g/mol
How much Na is needed to produce a 5 grams of table salt?
5 grams of table salt is 5 grams of NaCl. NaCl has a molar mass of 58.443 grams/mol, so 5 grams would be .0855 mol NaCl. In one mole of NaCl there is one mole of Na, so there would be .0855 mol Na, or 5.235 * 1022 atoms Na.
