Which value most closely represents the number of grams in 20 moles of carbon?
The number of grams in 20 moles of carbon is 240,22 g.
How many grams of Chlorine are in 7 grams of Sodium Chloride?
To find the answer, we multiply the 7 grams of NaCl by the ratio of the molar mass of chlorine over the molar mass of sodium chloride. By doing this, we find that there are about 4.25 grams of chlorine in 7 grams of NaCl.
A 1.22g sample of an unknown has a volume of 1.73cm3. What is the density?
They use a number called a mole. This many atoms of an element equals its atomic weight in the periodic table. Molecular weight is the sum of atomic weight. Silver has an atomic weight of 108 grams/mole and Chlorine is 35.4 grams/mole. This makes AgCl 108 + 35.4 = 143.4 grams/mole. The % Chlorine is the atomic weight of Chlorine divided by the molecular weight of AgCl. 1 mole of AgCl would contain 35.4 grams / 143.4 grams = 25% Chlorine by weight. 1.22 grams AgCl would contain (0.25)*(1.22) = 0.30 grams of Cl. To find the Chlorine in the unknown, divide the weight of Chlorine from the experiment by the initial weight of the unknown. 0.30 grams / 0.63 grams = 0.48 = 48% Cl by weight.
What is the maximum mass of aluminum chloride that can be formed when reacting 28.0g of aluminum with 33.0g of chlorine?
The formula of aluminium chloride is AlCl3. The atomic weight of aluminium is 27 and that of chlorine is 35.5. That means 35.5*3 grams of chlorine will combine with 27 grams of aluminium. So 33 grams of chlorine will combine with 8.37 grams of aluminium. The addition of both makes it 41.37 grams. In this reaction, the whole chlorine will be utilized and only part of the aluminium.
How many chloride molecules are in 35.5 grams of chloride gas?
Since 35.5 is the approximate atomic mass of chlorine and each molecule contains two atoms of chlorine, the number of molecules is about half of Avogadro's Number, 3.01 X 1023.
Which best represents the number of moles in exactly 64 grams of oxygen (O2)?
The number of moles in exactly 64 grams of oxygen (O2) is two.
What is the mass of 1.409 mole of the element chlorine in forms of grams?
1.409 moles chlorine (35.45 grams/1 mole Cl) = 49.95 grams of chlorine ==================
Which value most closely represents the number of grams in 20 moles of carbon?
The number of grams in 20 moles of carbon is 240,22 g.
How many grams of chlorine gas are in 6.82 x 1024 molecules of chlorine gas?
Chlorine gas (at standard temperature and pressure) consists of diatomic molecules. Therefore, in the specified number of molecules of chlorine gas there are 1.364 X 1025 atoms. The gram atomic mass of chlorine, which by definition consists of Avogadro's Number of atoms, is 35.453. Therefore, the mass of the specified number of molecules of chlorine gas is 35.453 X [(1.364 X 1025)/(6.022 X 1023)] or 803 grams, to the justified number of significant digits.
What mass of iodine contains the same number of atoms as 25.0 grams of chlorine?
861.9g i believe
Does one mole of chlorine gas have a mass of 35.45 grams.?
Yes, because the conversion for moles to grams is the number of moles multiplied by the atomic mass. So if there's only one mole, the number of grams would be the same as the atomic mass of chlorine, 35.45. This is true for all elements; one mole in grams is the same as the atomic mass.
Which value most closely represents the number of grams in 9.0 moles of calcium metal?
The number of grams in 9,0 moles of calcium metal is 360,7 g.
How many grams of Chlorine are in 7 grams of Sodium Chloride?
To find the answer, we multiply the 7 grams of NaCl by the ratio of the molar mass of chlorine over the molar mass of sodium chloride. By doing this, we find that there are about 4.25 grams of chlorine in 7 grams of NaCl.
How many grams are there in 0.100 mols of chlorine?
Multiply the moles given, by the atomic mass of chlorine and you have your answer. (3.55 Grams)
What number represents kg?
kg is a measurement unit. You can have any number of kilograms: there is no number representing it.
Is chlorine measured in grams?
all masses are measured in grams
