A sample of 0.53 grams of an ore contains 5.4 percent silver How many milligrams of pure silver are in the sample?
To calculate the amount of pure silver in the sample, multiply the mass of the ore by the percentage of silver: 0.53 grams * 5.4% = 0.02862 grams of silver. To convert grams to milligrams, multiply by 1000: 0.02862 grams * 1000 = 28.62 milligrams of pure silver in the sample.
How many moles of Cl are in a sample that contains 10.0 moles C2HCl3?
it wouldn't be moles of Cl it would be Cl2 as chlorine doesn't exist as an atom it exsists as two joined to form a compound this is very easy stuff the answer is 15 moles of Cl2 as there 30 moles of Cl hope this helps learn your moles it's easy stuff
A 10 ml sample of a substance has a mass of 20 grams what would be the mass of a 200 ml sample of the same substace?
The mass of the substance is 20 grams in a 10 ml sample. Therefore, the substance has a density of 2 grams/ml. For a 200 ml sample of the same substance, the mass would be 400 grams (200 ml x 2 grams/ml).
The mass of Denise's rock sample is 684 grams. The mass of Pauline's rock sample is 29,510 centigrams. How much greater is the mass of Denise's sample than Pauline's sample?
"centi" is 100. 1 centigram is 100 grams, so Denise's sample is 68,400 centigrams. 68400 - 29510 = 38890 centigrams or 388.90 grams.
A sample of Helium gas weighs 4.00 g (grams) and occupies 22.4 L (liters) when it is at 0 degree Celsius and 760 mm Hg pressure. What is the mass of the sample in grams?
The mass of the helium gas sample is already given as 4.00 grams. This value represents the weight of the gas under the specified conditions of temperature and pressure. Therefore, the mass of the sample is 4.00 grams.
How many grams is 56.8 grams?

How many grams of chlorine can you combine with thirty nine grams of potassium?
Balanced equation. 2K + Cl2 >> 2KCl 39 grams K (1mol K/39.10g )(1mol Cl/2mol K )(35.45g/1 mol Cl ) = 17.7 grams
How many grams are in 2.92 x 1023 atoms of tin?
There are 57.6 grams of tin in that sample.
A sample of 0.53 grams of an ore contains 5.4 percent silver How many milligrams of pure silver are in the sample?
To calculate the amount of pure silver in the sample, multiply the mass of the ore by the percentage of silver: 0.53 grams * 5.4% = 0.02862 grams of silver. To convert grams to milligrams, multiply by 1000: 0.02862 grams * 1000 = 28.62 milligrams of pure silver in the sample.
How many grams is 64 moles of Cl?
To find the mass of 64 moles of Cl (chlorine), you need to multiply the number of moles by the molar mass of Cl. The molar mass of Cl is approximately 35.45 g/mol. Therefore, 64 moles of Cl would be approximately 2267.2 grams (64 moles x 35.45 g/mol).
What is the method to calculate the mass in grams of each sample?
To calculate the mass in grams of each sample, you can use a balance or scale to measure the weight of the sample. The weight measured in grams is equivalent to the mass of the sample.
How many grams of chlorine gas Cl2 are given off if 7.5 grams of sodium chloride NaCl are decomposed?
To determine how many grams of chlorine gas (Cl₂) are produced from the decomposition of sodium chloride (NaCl), we start with the balanced chemical equation for the reaction: 2 NaCl → 2 Na + Cl₂. From the molar mass of NaCl (approximately 58.44 g/mol), 7.5 grams of NaCl corresponds to about 0.128 moles. According to the stoichiometry of the reaction, 2 moles of NaCl produce 1 mole of Cl₂, so 0.128 moles of NaCl would yield 0.064 moles of Cl₂. The molar mass of Cl₂ is approximately 70.90 g/mol, resulting in about 4.54 grams of Cl₂ being produced.
How many grams in 8 cl?
Since 1 centiliter (cl) is equal to 1 gram for water and other similar liquids, 8 centiliters would be equal to 8 grams.
What is 15 cl in grams?
15cL equals 0.15L* There are 100cL per liter
How many grams of Cl are in 435 g of CaCl2?
There are 2 moles of Cl in 1 mole of CaCl2. The molar mass of Cl is 35.45 g/mol. So, in 435 g of CaCl2, there would be 2 moles of Cl, which is equal to 70.9 g of Cl.
How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles of water molecules in a 27 gram sample of water. This is calculated by dividing the mass of the sample (27 grams) by the molar mass of water (18 grams/mol).
