For this you need the atomic (molecular) mass of HNO3. Take the number of moles and multiply it by the Atomic Mass. Divide by one mole for units to cancel. HNO3= 63.0 grams
2.00 moles HNO3 × (63.0 grams) = 126 grams HNO3
The total number of atoms in one mole of any substance is 6.02 X 10^23, otherwise known as Avogadro's number.
1 mole HNO3= 1+14+3x16= 63g
? = 0.135g
?= 0.135/63
Calculate the number of moles in 0.135 grams of HNO3?
0,135 grams of HNO3 is equal to 0,002 moles.
450 g of HNO3 is equal to 0,14 moles.
2.14 x 10-3
i love jonathan<3
2.14 x 10^(-3)
1 mole of HNO3 has 63,01 g.
0.135g

Molarity = moles/litermoles = 9.33 g Na2S x 1 mole/78 g = 0.1196 molesliters = 450 ml x 1L/1000 ml = 0.45 Lmolarity = 0.1196 moles/0.45 L = 0.266 M = 0.27 M (2 sig figs)
450 mg = 0.01587 oz
450 milligrams = 0.450 gram
1 mol of H2 is necessary.
450 moles of C2H4 contain 10.815,43 g carbon.
0.1125
Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters) 5M C6H12O6 = moles C6H12O6/0.450 liters = 2.25 moles C6H12O6 (180.156 grams/1 mole C6H12O6) = 405.351 grams of glucose ( you do significant figures )
I assume you mean 32.0 grams of NaOH and 450 milliliters of NaOH. Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters ) get moles of NaOH 32.0 grams NaOH (1 mole NaOH/39.998 grams) = 0.800 moles NaOH Molarity = 0.800 moles NaOH/0.450 liters = 1.78 Molar NaOH
450
There are 2.3888... 450 in 1075 1075 ÷ 450 = 2.3888...
The answer depends on 450 what. 450 hectolitres, 450 litres, 450 gallons or whatever will all give different answers.
45000 ÷ 100 = 450
450 of them.
450 prophets is the answer :)
There are infinitely many possible answers. One such is 450. That equals 450!
The person that will be president of the US in 450 years has not been born yet. In 450 years, the year will be 2463. On average, a present is between 40 and 60 years old.
