Answer:

0.198kg

Explanation:

because,

1kg = 1000g

so

198g = 0.198g

divide it by 1000 to get kg

How many miles of a gas at 100 c does it take to fill a 1.00 l flask to a pressure of 152kPa
Hatshy [7]

The complete question is as follows: How many moles of a gas at 100 c does it take to fill a 1.00 l flask to a pressure of 152kPa

Answer: There are 0.0489 moles of a gas at 100^{o}C is required to fill a 1.00 l flask to a pressure of 152kPa.

Explanation:

Given: Volume = 1.00 L,    

Pressure = 152 kPa (1 kPa = 1000 Pa) = 152000 Pa

Convert Pa into atm as follows.

1 Pa = 9.86 \times 10^{-6} atm\\152000 Pa = 152000 \times \frac{9.86 \times 10^{-6}atm}{1 Pa}\\= 1.5 atm

Temperature = 100^{o}C = (100 + 273) K = 373 K

Using the ideal gas formula as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

PV = nRT\\1.5 atm \times 1.0 L = n \times 0.0821 L atm/mol K \times 373 K\\n = \frac{1.5 atm \times 1.0 L}{0.0821 L atm/mol K \times 373 K}\\n = 0.0489 mol

Thus, we can conclude that there are 0.0489 moles of a gas at 100^{o}C is required to fill a 1.00 l flask to a pressure of 152kPa.

Why does increasing the temperature of two reactants in solution make a
gogolik [260]
The two molecules will only react if they have enough energy. By heating the mixture, you are raising the energy levels of the molecules involved in the reaction. Increasing temperature also means the molecules are moving around faster and will therefore "bump" into each other more often.

Except for the bolt, note the difference between the calculated volumes and the volume found by the displacement method. Which m
victus00 [196]

Answer:

See explanation

Explanation:

The most accurate method of determining the volume of an object, is the water displacement method. It has the peculiar advantage of working well with irregular solids.

There are often errors that prevent exact measurements of the volume of objects. This makes the water displacement method a preferred and easier method of determining the volume of an object.
