Density is found by dividing Mass by volume where mass is in grams and volume is in milliliters. 20 liters=20,000 ml so the calculation becomes 158/20,000 which yiels a result of .0079

What metal has a mass of 158g and a volume of 20mL?
What your tutor wants here is to find out is if, from the information given, you can determine the nature of the metal.Which you should be able to do. You should first determine the specific gravity, the weight in grams per cubic centimetre.And then explore the metals you know of to find one with similar density.158 / 20 = 7.9 g/cc. (Or since there are 1000 000 cc in a m3, multiply by 1 000 000.) which gives us 7.9000 tonnes/cubic metre.In a list of density of the elements, iron comes in at 7.87 tonnes per m3.Which for the present purposes looks a good candidate.
What is the molar mass for the following compound rounded to the nearest gram na2s2o3?
Na2S2O3 That's 2 sodiums at 23 each, 2 sulfurs at 32 each, and 3 oxygens at 16 each. 23+23+32+32+16+16+16=158g/mol.
Why could gliese 158g support life?
well Gleise 158 g is a "super earth" its roughly 5 times bigger than earth. supposedly it has water on it and it is in the "green zone" (the zone in which a planet can support life) and the "g" at the end on Gleise 158 G stands for Goldilocks which mean its a goldilocks planet ( a planet with life on it)

200g rice how many cups?
According to the nutritional facts it depends on the kind of rice. For example: -cooked brown rice 1 cup is 195g so 200g is just over 1 cup. -cooked white rice 1 cup is 158g so 200g about 1 1/4 cup.

What is the percent composition of KMnO4?
Potassium permanganate, or KMnO4, has a molar mass of 158g/mol. (39+55+16x4). % composition of K: 39/158=0.247=24.7%. % composition of Mn: 55/158=0.348=34.8%. % composition O: 64/158=0.405=40.5%.
What is the mass of 2.55 mol of KMnO4?
Number of moles= Mass/molar mass (g/mol) Hence Mass= mol × molar mass Mol=2.55 Molar mass of KMnO4= 39+55+(16×4)= 158g/mol Where K=39, Mn=55 and O =16 Hence Mass of KMnO4 in 2.55 mols of the compound= 2.55×158= 402.9g.
