Steam is just water. Water weighs the same per molecule regardless whether it is ice, water, or steam. That said, the molecular weight of water is right at 18 g/mole. So it seems that 9.0 grams of steam is about half a mole of water. Therefore we just divide avagrado's number by 2 and we get:
6.022 x 1023 / 2 = 3.011 x 1023 molecules
number of particles = moles x avogadro's constant therefore:
9moles x (6.02 x 10^23) = 5.418 x 10^24
that number is many trillions of molecules
90 g of water equals 30,11.10e23 molecules.
The answer is 13,048.1023 molecules.
12.01
At low concentrations, normality and molarity are about the same. So figure out how many grams are in a mole of KOH: K-39, O-16, H-1, so 39+16+1=56g/mol. 0.05 moles would be 56(.05)=2.8g, so dissolve 2.8 grams of KOH in a liter of water and you're there.
174 grams/mole. Looking at the Periodic Table: K is 39 grams/mole, S is 32 grams/mole, and O is 16 grams/mole.So: 2*39 + 1*32 + 4*16 = 174.

The atomic mass of potassium is 39 ,therefore the number of mole is 39 /39,which is 1then multiple by Avogadro number you get 6.022*10^24

39 grams of water is about 0.172 of a cup.
how many grams is 39cc?
78
1 kilogram = 1,000 grams 39 grams = 39/1000 = 0.039 kilograms
pch: 39 grams krazjj:)
Using google calculator 39 grams = 1.37568452 ounces OR using this conversion factor: 1 ounce = 28.3495231 V ounces / 39 grams = 1 ounce / 28.3495231 grams Solve for V V / 39 * 39 = 1 / 28.3495231 * 39 V = 39 / 28.3495231 V = 1.3756845172467821866111038742659 == 39 grams = 1.3756845172467821866111038742659 ounces

If liquid is water it will be 0.039 litters for other liquids it depends on specific gravity of liquid
39 grams is equivalent to....a mass of 39 grams !
39 pounds = 17 kilograms 690 grams
