Answer:
244.76
Explanation:
The weight of grams by 1.82 moles of lithium carbonate would be: 134.481438 So we need to use this equation to find mass by grams m × g = ms Where m is for moles, g for grams, and ms for mass. So now we need use this equation: 1.82 × 134.481438 = ? 1.82 × 134.481438 = 244.75621716 244.75621716, rounded-up (to the nearest-tenths place) is 244.76. So now you have it! The mass of 1.82 moles of lithium carbonate is 244.76!
Answer:
14.9802 grams of estrogen must be added to 216.7 grams of benzene.
Explanation:
The relative lowering of vapor pressure of solution containing non volatile solute is equal to mole fraction of solute.
Where:
= Vapor pressure of pure solvent
= Vapor pressure of the solution
= Number of moles of solvent
= Number of moles of solute
Mass of 0.05499 moles of estrogen :
= 0.05499 mol × 272.4 g/mol = 14.9802 g
14.9802 grams of estrogen must be added to 216.7 grams of benzene.

<em>atmosphere (air).</em>
Units of measure is defined as a the magnitude of a certain quantity. There are a lot of units that we can use for mass. Kilograms, grams, tons, pounds and slugs are some of the examples. There are some units where certain prefixes changes its magnitude. One thousand grams is one kilogram. One thousand mg is one gram. 5.63 grams is 5,630 mg and 0.00563 kg is 5.63 grams. Hence the answer here is 0.563 hg.
