The answer is 108 g water.

According to the periodic table, silver (Ag) has an atomic mass of about 108 grams per mole. If you have 802 grams, set up a direct proportion where 108/1=802/x and solve for x. You get about 7.43 moles of silver.

The answer is 6 moles.

One mole weights 26.98 grams, so it is arouind 27 g. So 4 moles weight almost 108 grams.

108 grams = 3.81 ounces.

One molecule of P2O3 = 1 mole. Go to the periodic table P = 30gm x 2 = 60 gm. O= 16 gm x 3 = 48 mg. Total is 60 + 48 = 108 gm is the weight of one molecule which is also the number of grams in 1 mole (remember 1 mol = 1 mole). So since you have 37.9 grams divide this by 108 and you have .35 moles.

First, divide that very large number of molecules by Avogadro's constant, which is the number of particles in 1 mole of any substance: 2.5x10e23/6.02x10e23 = 0.415 moles. Next, calculate the number of grams in mole of silver nitrite (AgNO2): Ag=108, N=14, 2(O)=32; 108+14+32=154. Finally, multiply moles by grams per mole: 0.415(154) = 63.9g.

I assume you mean 3.55 grams of silver. Don't forget your units! Silver (Ag, #47) has an atomic mass of about 108 grams per mole. Set up a direct proportion: 108/1=3.55/x, where x is the unknown number of moles in 3.55 grams Ag. Solve for x to get approx. 0.033 moles Ag. Multiply this number by Avogadro's constant of 6.02x1023 to get the number of representative particles. So, 0.033(6.02x1023)=1.99x1022 atoms of silver.

30 grams are the same as 1ounce so 108 divided by 30 equals 3.6 ounces This is the average weight of an Einstein Bagel.

in dimensional analysis (for chemistry) your usually converting substances to moles or grams to figure out whatever you need for the problem. For units, you always want the units to cancel out as 1/7 * 7 cancels out to 1/1 or 1.for example, if i want to find the molar mass of 3.00 moles of Carbon (C), this is your set up:(3.00 moles Carbon)(36.03 grams Carbon/1mole Carbon)=108.09/1 grams Carbon=108 grams Carbon(using sig. figs)in the problem above, since moles are the numerator, and you want to find how many grams are in 3 moles of carbon, you want to set up a ratio of moles per grams. Ratios can be flip flopped based on which units you need. So i look at the periodic table and see there are 12.01 grams per 1 mole, setting the ratio up so that when it multiplies 3 moles of carbon, the moles cancel and im left with grams of carbon, the units i want. It seems complicated but gets easier with practice.

mw (molecular weight) of C =12 mw of H = 1 12(8) +12(1)=108 g 108g = 1 mol so 5.9 moles = 108 (5.9)= 637.2 g 5.9moles of C8H18=637.2 g

Ar of Ag = 108g/mol Ar of Cl = 35.5/mol Mr of AgCl = 108+35.5 = 143.5g/mol Using the formula : mass = Mr x number of moles mass = 143.5g/mol x 3.0mols = 430.5g

The reaction between Isopropyl alcohol and oxygen is 2 C3H8O + 9 O2 equals 6 CO2 + 8 H2O. So for every mole of isopropyl alcohol, 4.5 moles of oxygen are consumed. 6.5 grams of C3H8O is .108 moles and 12.3 grams of O2 is .384 moles. This means that O2 is the limiting reactant as it needs .486 moles of O2 to finish.

Silver(I) chloride has a molar mass of 143.5 g/mol (108+35.5 from the periodic table). This represents the number of grams in 1 mole of that compound. You have 3 moles, so 3(143.5)=430.5 grams.

Oxidation-reduction reaction:Ag^+(aq) + Al(s) ===> Ag(s) + Al^3+ or looked at another way... 3AgNO3(aq) + Al(s) ===> Al(NO3)3(aq) + 3Ag(s) moles AgNO3 present = 92.8 g x 1 mole/170 g =0.546 moles moles Al present = 1.34 g x 1 mole/26.9 g = 0.0498 moles Al is limiting based on mole ratio of 3 AgNO3 : 1 Al moles Ag(s) produced = 0.0498 moles Al x 3 moles Ag/mole Al = 0.1494 moles Ag mass of Ag = 0.1494 moles Ag x 108 g/mole = 16.1 g Ag formed

The atomic mass of the element silver, Ag is 108Amount of Ag = mass of sample/molar mass = 108/108 = 1.00 So, there is 1.00mol of silver in a 108g pure sample.

Using your molar mass. 0.0001 grams silver (1 mole Ag/108 grams)(6.022 X 1023/1 mole Ag) = 5.58 X 1017 atoms of silver =====================

12oz.: 39 grams 20oz.: 65 grams 1 liter: 108 grams

The mass of water is 108 g.

108 calories per 27 grams of cereal (one serving)

that is approximately 20 tsp

There are 39 grams in a 12 ounce can. There are 65 grams in a 20 ounce bottle and 108 grams in a 1 liter bottle.

The average lemon weighs about 108 grams which is about 3.8 ounces.
