SpyIntel [72]
With all of the information given (pressure, volume, temperature, and the molar mass), we need a formula that relates this all together. The formula we need is the ideal gas law, PV=nRT. Since the pressure is defined in millimeters of mercury, we need the R value that correlates with this, which is 62.4; on top of this, we need the temperature in Kelvin - simply add 273.15 to convert from Celsius. With all of this information, simply plug-and-chug:

PV=nRT
(800)(3.7) = n(62.4)(37 + 273.15)
n = 0.1529 moles

Finally, the problem is asking the amount of air in grams. We have moles, so all we need to do is multiply that value by the molar mass.

0.1529 moles x 29 grams per mole =
4.435 grams of air

The balloon has 4.435 grams of air inside it.

Hope this helps!

Ede4ka [16]

Answer:

i. Molar mass of glucose = 180 g/mol

ii. Amount of glucose = 0.5 mole

Explanation:

<em>The volume of the glucose solution to be prepared</em> = 500 cm^3

<em>Molarity of the glucose solution to be prepared</em> = 1 M

i. Molar mass of glucose (C_1_2H_6O_6) = (6 × 12) + (12 × 1) + (6 × 16) = 180 g/mol

ii.<em> mole = molarity x volume</em>. Hence;

amount (in moles) of the glucose solution to be prepared

                 = 1 x 500/1000 = 0.5 mole

Plz help studying for final I think its D but not sure
balandron [24]
Yes it is option D
simply if 1 mole of H2SO4 require 2 moles of NaCN, i.e. the double amount. so 3.6 moles will require 7.2 moles of NaCN
