Baloon with 3 moles og oxygen at 1 atm.The temperature of the balloon is <u>4 Kelvin</u>.

An ideal gas is a theoretical gas composed of many randomly transferring factor particles that aren't difficult to interparticle interactions. the best gasoline idea is beneficial because it obeys the precise gas law, a simplified equation of country, and is amenable to evaluation under statistical mechanics.

An ideal gas is described as one for which both the extent of molecules and forces between the molecules are so small that they have got no effect at the behavior of the gas. The real gas that acts almost like a really perfect gasoline is helium. that is due to the fact helium, in contrast to maximum gases, exists as an unmarried atom, which makes the van der Waals dispersion forces as low as viable

Using the ideal gas equation:-

Given;

P₁ = 1 atm

V₁ = 100  L

n = 3

r = 8.314

T = PV/nR

  = 1 × 100 / 3 × 8.314

 = 4 K

If you dissolve 8.50 g of ca(no3)2 in 755 ml of distilled water what is the concentration in molarity of the calcium nitrate sol
Zanzabum
Molarity is defined as the number of moles of solute in 1 L of solution 
the mass of Ca(NO₃)₂ present - 8.50 g
therefore number of moles of Ca(NO₃)₂ - 8.50 g / 164 g/mol = 0.0518 mol
the volume of solution prepared is 755 mL 
therefore if there are 0.0518 mol in 755 mL 
then in 1000 mL the number of moles - 0.0518 mol / 0.755 L 
molarity is therefore - 0.0686 M

  • Mass=5kg=5000g
  • Volume=50cm^3

\\ \rm\longmapsto Density=\dfrac{Mass}{Volume}

\\ \rm\longmapsto Density=\dfrac{5000}{50}

\\ \rm\longmapsto Density=100g/cm^3

Alright, now you actually have an aqueous solution of your salt! Though perhaps not all of the salt has dissolved yet, but we'll
erica [24]

If not all of the salt has dissolved then the measurement of the concentration at the time is really inaccurate.

<h3>What is concentration?</h3>

The concentration is the amount of substance that is present in solution. We know that we can not measure the concentration unless all of the solute have been dissolved in the solution.

Thus, if not all of the salt has dissolved then the measurement of the concentration at the time is really inaccurate.

A 10-ft moving truck has a volume capacity of 402 cubic feet, which is equivalent to 1.138 x 10⁷ milliliters. What mass of silve
steposvetlana [31]

Answer:

The mass of silver is 1.19\times 10^{14}\ Mg

Explanation:

Given that,

The volume of the truck is 402 cubic feet or 1.138 x 10⁷ mm.

The density of silver is 10.49 g/mL.

We need to find the mass of silver that will fit in this moving truck. Density equals mass divided by volume. So,

d=\dfrac{m}{V}\\\\\text{where m is mass}\\\\m=d\times V\\\\m=10.49\ g/mL\times 1.138 \times 10^7\ mL\\\\m=119376200\ g

1 gram = 10⁻⁶ Megagram

119376200=1.19\times 10^{14}\ Mg

Hence, the mass of silver is 1.19\times 10^{14}\ Mg
