How many moles are present in 205g of helium?
To calculate the number of moles, you need to divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4 g/mol. Therefore, the number of moles in 205g of helium would be 205g / 4g/mol = 51.25 mol.
How would you find the percent of 17g sucrose in 188g of water?
To find the percent of 17g sucrose in 188g of water, first calculate the total mass: 17g (sucrose) + 188g (water) = 205g. Then, divide the mass of sucrose (17g) by the total mass (205g), and multiply by 100 to convert to a percentage. The percent of 17g sucrose in 188g of water would be roughly 8.29%.
What is percent of 17g sucrose in 188g of water?
To find the percentage of 17g of sucrose in 188g of water, first calculate the total weight by summing both amounts (17g + 188g = 205g). Then, divide the weight of the sucrose by the total weight and multiply by 100 to get the percentage: (17g / 205g) * 100 β 8.29%.
How many moles dose 11 grams of silicon contain?
11 g x 1 mol Si/28.0855 g Si= 0.39 mol Si 205g He x 1mol He/4.002602 g He=51.2 mol He
How many moles does 205 g of helium contain?
Helium exists as a monatomic noble gas. Its atomic mass is 4.0 as can be obtained from the periodic table. The amount of helium in a 205g pure sample is given by 205/4.0 which equates to roughly 51 moles.
How many ounces is 205 grams?

How many cups in a pound of shortening?
One tablespoon of solid shortening weighs 13 grams (from label). There are 16 tablespoons in one cup, so 13 x 16 = 208 grams. One-half cup of shortening weighs 104 grams. One-third cup of shortening weighs 69 grams. One-fourth cup of shortening weighs 52 grams. This is the easiest way to weigh shortening. Just be sure to zero out the scale before adding shortening to the cup or bowl.
