A cube has sides that are 0.03 m . What is the volume of the cube in liters?
Marizza181 [45]

Answer:

0.027 litres

Explanation:

volume of cube = length × base area

volume of cube = 0.03m ×( 0.03m × 0.03m )

volume of cube = 0.03m × ( 0.0009m^2 )

volume of cube = 0.000027m^3

1 cubic metre = 1000 litres

0.000027m^3 = 0.027 litres

What is the ph of a solution with [h3o+] = 1 × 10-9 m?
FrozenT [24]
PH scale is used to determine how acidic, basic or neutral a solution is
pH can be calculated using the H₃O⁺
ph can be calculated as follows
pH = - log[ H₃O⁺]
[H₃O⁺] = 1 x 10⁻⁹
pH = - log [1 x 10⁻⁹]
 pH = 9
pH of solution is 9

What is the maximum mass of b4c that can be formed from 2.00 moles of boron(iii) oxide?
anzhelika [568]

The maximum mass of B₄C that can be formed from 2.00 moles of boron (III) oxide is 55.25 grams.

<h3>What is the stoichiometry?</h3>

Stoichiometry of the reaction gives idea about the relative amount of moles of reactants and products present in the given chemical reaction.

Given chemical reaction is:

2B₂O₃ + 7C → B₄C + 6CO

From the stoichiometry of the reaction, it is clear that:

2 moles of B₂O₃ = produces 1 mole of B₄C

Now mass of B₄C will be calculated by using the below equation:

W = (n)(M), where

  • n = moles = 1 mole
  • M = molar mass = 55.25 g/mole

W = (1)(55.25) = 55.25 g

Hence required mass of B₄C is 55.25 grams.
