The Atomic Mass of potassium, K is 39.1.
This means that 1 mole of potassium has a mass of 39.1g.
Mass of 0.5mol of K = 0.5 x 39.1 = 19.6g

If the solid after heating has a molar mass of 208 grams per mole and a formula of XY what is the formula of the hydrate?
Moles of the soild = 1.78/ 208 = .00856 moles of H2O = 0.90/ 18 =.05 therefore number of moles of water for 1 mole of solid = .05/.00856 = approx 6
Approximately how many moles are in 300 grams of sulfur?
I mole of sulfur atoms is 32 g. Thus there are 300/32 moles in 300 g, i.e. 9.375 moles.
What is the mass in grams of 0.50 moles of BeCI2?
137.4 g First you need to calculate the molar mass of the molecule. Be = 9.01 g/mol C = 12.01 g/mol I = 126.9 g/mol Thus BeCI2 is equivalent to ( 9.01 + 12.01 + 2(126.9) ) g/mol or 274.82 g/mol. Then, using conversions, you multiply the amount you have by the molar mass so that: (.05 mol BeCI2)*(274.82 g/mol). The moles cancel out and you are left with a weight of 137.41 g.
How many grams is .05 ounces of gold?
.05 ounces = 1.41748 grams
How many kilograms in 500mg?
0,0005 kg
How many kilograms is in 05 grams in grams?
Divide by 1000 to convert grams into kilograms
How many kilograms is 50 grams?
One kg = 1000 grams. So one gram is 10^-3 kilograms. One milli gram is 10^-3 gram = 10^-6 kg. Kilograms and grams are both the metric units of mass. So the answer in kg is 0.050
Is 05 grams of meth a usable quantity?

How do you prepare 1 ltr koh 0.05N?
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.
