Answer:

Mass 1=3M

Mass 2=?

Volume1=75mL

Volume2=250mL

By using molarity formula:

<u>mass1*volume 1=mass2*volume 2</u>

3M*75=mass2*250

mass2=225/250

mass2:0.9M

<h3>the molarity of a solution is 0.9M.</h3>

  • M1=3M
  • M2=?
  • V1=75mL
  • V2=250mL

We know

\boxed{\Large{\sf M_1V_1=M_2V_2}}

\\ \Large\sf\longmapsto M_2=\dfrac{M_1V_1}{V_2}

\\ \Large\sf\longmapsto M_2=\dfrac{3(75)}{250}

\\ \Large\sf\longmapsto M_2=\dfrac{225}{250}

\\ \Large\sf\longmapsto M_2=0.9M

Write a balanced chemical equation for the complete combustion of C3H7BO3, a gasoline additive. The products of combustion are C
nexus9112 [7]

Answer:

2C₃H₇BO₃ + 8O₂ → 6CO₂ + 7H₂O + B₂O₃.

Explanation:

  • For balancing a chemical equation, we should apply the law of conversation of mass. It states that the no. of atoms in the reactants side is equal to that of the products side.

So, the balanced equation:

<em>2C₃H₇BO₃ + 8O₂ → 6CO₂ + 7H₂O + B₂O₃.</em>

It is clear that 2.0 moles of C₃H₇BO₃ is completely burned in 8 m oles of oxygen and produce 6 moles of CO₂, 7 moles of H₂O and 1 mole of B₂O₃.

Oxygen gas is collected at a pressure of 123 kPa in a container which has a volume of 10.0L. What temperature must be maintained
Morgarella [4.7K]
Given:

P = 123 kPa
V = 10.0 L
n = 0.500 moles
T = ?

Assume that the gas ideally, thus, we can use the ideal gas equation:

PV = nRT

where R = 0.0821 L atm/mol K

123 kPa * 1 atm/101.325 kPa * 10.0 L = 0.500 moles * 0.0821 Latm/molK * T

solve for T 

T = 295.72 K<span />
