How many moles are in 4.5 g of AgNO3?
The number of moles is given by :n = m / Mn = ( 4.5 g ) / ( 169.9 g / mol ) = 0.02649 moles
How many moles are there in 5 grams of silicon dioxide?
number of moles=mass/molar mass =5/(28+32) =0.83 mol
What is the mass of 5 moles H2?
The mass of 5 mol H2 is 10,08 g.
How many oxygen atoms in 2.15 mol of N2O?
firstly, you cannot have 1.20105 molecules, it is physically impossible to have a non-integer number of molecules. But I will assume you mean 1.20105 mol. Simply multiply the number of mols of oxygen atoms by avagadros number so 1.20105 mol of n205 = 1.20105*5mol of oxygen atoms. 1.20105 x 5 x 6.022e-23 is your answer
A sample of gold has a mass of 5.00 x 10-3g. what amount of gold in atoms does the sample contain?
5x10-3 g divided by m.wt. of gold (197 g/mol) equals 2.5x10-5 mol gold.2.5x10-5 mol gold multiplied by Avogadro's Number (6.023x10+23 atoms/mol) equals 1.5x10+20 atoms.
The number of moles of h2o formed when 1 mole of o2 reacts with c5h12 in the reaction c5h12 plus 8o2 equals 5co2 plus 6h2o is?
C5H12 + 8 O2 --> 5 CO2 + 6 H2O (1 mol O2)(6 mol H2O/8 mol O2) = 0.75 mol H2O
How many NaCl formula units does it contain?
0,16 mg NaCl is equivalent to 2,7.10-5 mol.
What would be the mass of 5 mol of ammonia Calculate the number of ammonia molecules?

What is a number plus 7 is greater than 2?
n + 7 > 2 which is equivalent to n > -5
what is 1 plus 4 plus 5?
The mathematical equation of 1 plus 4 plus 5 is equivalent to 10.
What is the weight of 1 liter of 5 Molar sodium hydroxide?
5 M NaOH = 5 mol/L NaOH. 1 mol of NaOH = 40 g NaOH. You can get the number of grams by multiplying 5 mol/L and 40g/mol. This will give you 200g/L. Just multiply by the volume, which is 1 Liter, and you will get 200 g of NaOH.
What is the equivalent to 4t-7t plus 5?
-3t+5
What is the answer to this problem If 1 plus 5 equals 12 and 2 plus 10 equals 24 and 3 plus 15 equals 36 then 5 plus 25 equals what?
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
