3.18 mol 70.0gN2O x 1mol N2O/44.013g x 2mol N/1mol N2O
To convert mmol to moles, divide by 1000. Therefore, 2.55 mmol is equal to 0.00255 moles.
5.0 grams CO2 (1mol CO2/44.01g) = 0.11 moles CO2
To find the number of moles of atoms in 4.1 x 10^(-12) g of oxygen, you first convert the mass to moles by dividing by the molar mass of oxygen (16 g/mol). 4.1 x 10^(-12) g / 16 g/mol = 2.56 x 10^(-13) moles of oxygen atoms.
In one (1) molecule CO2 there are 3 atoms ( 1 C-atom and 2 O-atoms), so in 5 molecules CO2 (5CO2) there are 5 x 3 (= 15) atoms. Thus fifteenis the answer to you.
1.50 X 10^23 molecules of NH3 is equivalent to 0.25 moles of NH3.
To calculate the number of moles in 100 g of MgCO3, you need to first determine the molar mass of MgCO3, which is 84.31 g/mol. Divide the given mass (100 g) by the molar mass to find the number of moles. In this case, 100 g / 84.31 g/mol ≈ 1.19 moles of MgCO3.
To find the number of moles in 76 grams of fluorine, you first need to determine the molar mass of fluorine, which is approximately 19 grams per mole. Then, you divide the given mass (76 grams) by the molar mass of fluorine to get the number of moles. In this case, 76 grams of fluorine is equal to approximately 4 moles.

The molar ratio of hydrogen to nitrogen is 4:28, which simplifies to 1:7 when divided by their respective molar masses. The empirical formula would be HN2, as the ratio reduces to the simplest whole number values.
To convert mmol to moles, divide by 1000. Therefore, 2.55 mmol is equal to 0.00255 moles.
To find the number of moles of NO in 345.6 g, first calculate the molar mass of NO (28.01 g/mol for nitrogen + 16.00 g/mol for oxygen). Then divide the given mass by the molar mass to get the number of moles.
To find the number of moles in 234g of NaCl, divide the given mass by the molar mass of NaCl. The molar mass of NaCl is 58.44 g/mol (sodium = 22.99 g/mol, chlorine = 35.45 g/mol). So, 234g ÷ 58.44 g/mol = 4 moles of NaCl.
0.3 moles K (6.022 X 10^23/1mol K) = 1.8 X 10^23 atoms of K
the equation of this reaction is C + O2 = CO2 (s) (g) (g) according to this reaction 1mol of Carbon react with same number of moles of Oxygen. and this combination gives 1mol of CO2 as result. so first we have to find the number of moles in the weight we are going to use. 12 grams of carbon contains 1mol so 6 grams of carbon contains ( 1/12 )*6 = 0.5mol 32 grams of Oxygen contains 1mol 16 grams of Oxygen contains ( 1/36 )*16 = 0.5mol as 1mol of C react with 1mol of O2,0.5mol of C react with 0.5mol of O2. this produces equal number of moles (0.5mol) of CO2.
To determine the number of hydrogen molecules produced, you first need to find the moles of zinc reacting. Then, using the balanced chemical equation, you can determine the moles of hydrogen produced. Finally, convert moles of hydrogen to molecules using Avogadro's number (6.022 x 10^23 molecules/mol).
5.0 grams CO2 (1mol CO2/44.01g) = 0.11 moles CO2
