you need to know the molar mass. Lets say the molar mass is M grams / mole
450 micromoles x 1 mole/1000 micromoles x M grams / mole
x 109 nanograms / gram = 450 x M x 109 nanograms <-- answer
842
450 kelvin is 176.85 Celsius. To convert Kelvin to Celsius you just subtract 273.15 by the Kelvin temperature that you are trying to convert.
0.1125
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)
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 grams2.00 moles HNO3 × (63.0 grams) = 126 grams HNO3
450 moles of C2H4 contain 10.815,43 g carbon.
450 g water 100g sugar 30g vinegar 2g salt for vinegar use2.4 g of acetic acid
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

Divide by 1000.
If you are wondering how to convert miles to meters .we need not have to worry we must know the relation between these units for conversion . 1 meter =0.00062 miles. Lets convert 450 meter to miles now. 450 m =0.00062 * 450 . =0.279 miles. 0.279 miles are there in 450 meters.
