What is the total number of moles in 80.0 grams of C2H5Cl?
The molar mass of an element is its atomic weight in grams. The atomic weight is on the periodic table. 1 mole C = 12.0107 g C. To calculate the number of moles in 80 g of C, do the following: 80 g C x (1 mole C/12.0107 g C) = 6.66 mole C = 7 mole C* *This answer has been rounded to the proper number of significant figures. When multiplying or dividing, the answer is rounded to the fewest significant figures used in the calculation. 80 only has one significant figure. Refer to the related link below concerning significant figures.
How many grams are in 11 pounds?
4989.52 grams to 11 pounds.
11 grams is equal to how many pounds?
11 grams is equal to about 0.02425 pounds.
How many grams in 6 pounds 11 ounces?
There are approximately 3087 grams in 6 pounds 11 ounces.
How many grams is 11 pounds?
11 pounds is equivalent to approximately 4990 grams.
How many grams of NaCl are present in 11 moles?
Remember the 'moles' equation/ moles = mass(g) / Mr (Relative molecular mass). By algebraic rearrangement mass (g) = moles X Mr . moles(NaCl) = 11 Mr(NaCl) = 23 + 35.5 = 58.5 (From Periodi Table) Hence mass(NaCL) = 11 x 58.5 = 643.5 grams.
How many moles does 11 g of silicon contain?
Ah, let's paint a happy little picture with some silicon! To find out how many moles are in 11 grams of silicon, we need to use the molar mass of silicon, which is about 28.09 grams per mole. So, by dividing 11 grams by the molar mass, we find there are approximately 0.39 moles of silicon in 11 grams. Just remember, in the world of chemistry, every little bit counts!
What is the mass of 11 moles of KCl?
The atomic mass of potassium is 39 The atomic mass of chlorine is 35.5 The formula mass of KCl is the sumof these. This is the mass in grams of one mole of KCl. Use this as a conversion factor to find mass of 11 moles
How many moles are in 3.4x10-7 grams of silicon dioxide?
To find the number of moles, we need to convert the given mass in grams to moles. The molar mass of silicon dioxide (SiO2) is approximately 60 grams/mol. Number of moles = (3.4x10^-7 grams) / (60 grams/mol) = 5.7x10^-9 moles.
How many moles in 11.g of Ti?
To find the number of moles in 11 grams of Ti (titanium), you need to divide the given mass by the molar mass of Ti, which is approximately 47.87 g/mol. So, 11 grams of Ti is equivalent to 0.23 moles (11g / 47.87 g/mol = 0.23 mol).
How many moles of water are present in 180 grams of water?
11
How many grams of v203 would you need to have 7.56e11 atoms of oxygen?
To determine the grams of V2O3 needed, we first find the number of moles of oxygen atoms in 7.56e11 atoms. Then, using the molar ratio in V2O3 (2 moles of oxygen for every mole of V2O3), we find the moles of V2O3. Finally, we convert moles to grams using the molar mass of V2O3.
How many moles of carbon are there from the original sample of 11.0 grams of carbon dioxide and 4.50 grams of water with a combustion of 7.50 grams?
Look up the molecular weight of carbon dioxide in the periodic table. The formula for carbon dioxide is CO2, which means one atom of carbon and two atoms or oxygen per molecule of carbon dioxide. Carbon has molecular weight of 12. Oxygen molecular weight is 16. Total 12+16+16= 44 11 grams/44 grams/mole=0.25 moles of carbon The grams of water and combustion of 7.5 grams are totally irrelevant. They are only given to possibly confuse you.
What is the number of moles in 508 g of ethanol?
To find the number of moles in 508g of ethanol (C2H5OH), first calculate the molar mass of ethanol: 2(12.01) + 6(1.01) + 1(16.00) = 46.08 g/mol. Next, divide the given mass by the molar mass to find the number of moles: 508g / 46.08 g/mol ≈ 11 moles.
What volume in mL of a 1.06 M NaOH solution is required to neutralize 11 g of HCl?
Balanced equation. NaOH + HCl -> NaCl + H2O all one to one. find moles HCl. 11 grams HCl (1 mole HCl/36.458 grams ) = 0.3017 moles HCl Moles HCl same as moles NaOH Molarity = moles of solute/Liters of solution 1.06 M NaOH = 0.3017 moles NaOH/liters of solution = 0.2846 Liters this is equal to..... 285 milliliters of NaOH needed
How many grams of H2 are needed to reduce 5.51 moles of CuO in the reaction?
11 g hydrogen are needed.
What is the mass of 0.125 mole of copper (11)oxide?
To find the mass of 0.125 moles of copper (II) oxide (CuO), you need to determine the molar mass of CuO which is 79.55 g/mol. Multiply the molar mass by the number of moles to get the mass. Therefore, 0.125 moles of CuO would have a mass of 9.94 grams.
