Answer:

0.182M Ba(OH)₂

Explanation:

The reaction of barium metal (Ba) with H₂O is:

Ba + 2H₂O → Ba(OH)₂ + H₂

25g of Ba are:

25g Ba × (1mol / 137.327g) = 0.182 moles of Ba. Based in the reaction, 1 mole of Ba produces 1 mole of Ba(OH)₂. That means you will produce <em>0.182 moles of Ba(OH)₂. </em>If the whole volume of your solution is 1.00L, the concentration of barium hydroxide is:

0.182 moles of Ba(OH)₂ / 1.00L = <em>0.182M Ba(OH)₂</em>

A tank holds 6.90 m3 of water. What is the volume in ft3? (3.28 ft = 1 m, Remember significant figures, but this answer does not
AleksAgata [21]

Volume of tank = 6.9 m^{3} (given)

Since, 1 m = 3.28 ft

So,  

1 m^{3} = 35.287 ft^{3}

For 6.9 m^{3}:

6.9\times 35.287 ft^{3} = 243.4803 ft^{3}

The significant rule for multiplication, states that the number of significant figures in the answer obtained by multiplication is determined by the value with the lowest number of significant digits.

Since, the minimum number of decimal places in the above multiplication operation is 1 so, the final result must be upto 1 decimal place only.

243.4803 ft^{3} \simeq 243.5 ft^{3}

Hence, volume in ft^{3} is 243.5.
