7.9g/ML
The metal's density is 7.9 g/mL
Density = Mass/Volume. Without information about the volume it is not ossible to answer the question.
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.
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.

The molar mass of water (H2O) is 18. Ice is water in it's solid state.
There are:approx 205 calories in one cup (5.6 oz, 158g) of long grain, white, cooked rice.
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.
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.
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)
im pretty sure it ways 158g and theirs not that much phones that way alot around these dady accept for the house phones and i would like a phone that doesnt weigh much and that is'nt is to brake. And the Motorola Photon 4G smartphone has the following specifications Dimensions: 4.99" x 2.6" x .48"
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%.
