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.
What number represents kg?
kg is a measurement unit. You can have any number of kilograms: there is no number representing it.
What mass of oxygen gas contains the same number of moles as 56 gram of Sulphur?
To determine the mass of oxygen gas containing the same number of moles as 56 grams of sulfur, calculate the molar mass of sulfur (32 g/mol) and use it to find the number of moles in 56 grams. Then, since the molar ratio of sulfur to oxygen in a compound is 1:1, this same number of moles of oxygen gas would weigh 32 grams.
How many o atoms are present in 50gram of caco3?
There are 2 oxygen atoms in one molecule of CaCO3. To calculate the number of oxygen atoms in 50 grams of CaCO3, you first need to find the number of moles of CaCO3 using its molar mass. Then, multiply the number of moles by the number of atoms of oxygen per molecule of CaCO3 (2) to find the total number of oxygen atoms.
A compound is formed when 48 grams of carbon 8 grams of hydrogen and 68 grams oxygen combine what is the percent by mass of oxygen?
The percentage of oxygen is 54,84 %.
Which best represents the number of moles in exactly 84 grams of chlorine (Cl2) gas?
The molar mass of chlorine gas (Cl2) is 70.91 g/mol. To convert grams to moles, you divide the mass (84 g) by the molar mass (70.91 g/mol). So, 84 grams of chlorine gas is equal to approximately 1.18 moles.
How many atoms of oxygen are in 3.120 grams of oxygen gas?
To find the number of oxygen atoms in 3.120 grams, we need to first calculate the number of moles using the molar mass of oxygen gas. The molar mass of oxygen gas is 32 g/mol. So, 3.120 grams is equal to 0.0975 moles. Each mole of oxygen gas contains 2 oxygen atoms, so there are 0.195 moles of oxygen atoms in 3.120 grams. Finally, using Avogadro's number (6.022 x 10^23), we find that 1.17 x 10^23 oxygen atoms are present in 3.120 grams of oxygen gas.
How do you calculate how many oxygen atoms are there in 2.50 grams of oxygen gas?
To calculate the number of oxygen atoms in 2.50 grams of oxygen gas (O2), you will first need to convert grams to moles using the molar mass of O2 (32 g/mol). Then, use Avogadro's number (6.022 x 10^23) to determine the number of oxygen molecules in moles. Since there are 2 oxygen atoms in each O2 molecule, you will multiply the number of moles by 2 to find the total number of oxygen atoms.
How many moles of AgNO3 does 85 grams of AgNO3 represents?
To find the number of moles, you need to divide the given mass (85 grams) by the molar mass of AgNO3 (169.87 g/mol). 85 grams of AgNO3 represents 0.500 moles.
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.
What is the mass in grams of 6.02 x 1023 atoms of sulfur?
The molar mass of sulfur is 32.06 g/mol. To find the mass of 6.02 x 10^23 atoms of sulfur, first calculate the number of moles by dividing the number of atoms by Avogadro's number (6.02 x 10^23 atoms/mol). Then, multiply the number of moles by the molar mass of sulfur to get the mass in grams.
How much mass 6.02 x 1023 atoms of oxygen have?
Just about 16 grams as what you have written in you question is Avogadro's number, which is a mole of anything. Oxygen is 16 grams per mole.
What number represents kg?
kg is a measurement unit. You can have any number of kilograms: there is no number representing it.
How do you accurately read grams on a scale?
To accurately read grams on a scale, place the object on the scale and wait for the reading to stabilize. Ensure the scale is set to grams and read the number displayed on the screen. This number represents the weight of the object in grams.
What mass of oxygen gas contains the same number of moles as 56 gram of Sulphur?
To determine the mass of oxygen gas containing the same number of moles as 56 grams of sulfur, calculate the molar mass of sulfur (32 g/mol) and use it to find the number of moles in 56 grams. Then, since the molar ratio of sulfur to oxygen in a compound is 1:1, this same number of moles of oxygen gas would weigh 32 grams.
What does a million equal in grams?
A million is a number, which is an abstract concept. It has no mass and so, in terms of grams, it would measure exactly zero.
How many grams are contained in 0.644 mol oxygen?
To find the grams in 0.644 mol of oxygen, you need to multiply the number of moles by the molar mass of oxygen. The molar mass of oxygen is approximately 16 g/mol. Therefore, 0.644 mol of oxygen would contain 0.644 mol x 16 g/mol = 10.304 grams of oxygen.
