Answer:

2.25 × 10^1 and It has 3 significant figures. In scientific e-notation it is written as 2.25e+1.

Explanation:

1) Move the decimal 1 times to left getting m = 2.25, is greater than or equal to 1 but less than 10

2) Since we moved the decimal to the left the exponent n is positive n = 1

3) Write in the scientific notation form, m × 10n = 2.25 × 10^1

If this energy were used to vaporize water at 100.0 ∘C, how much water (in liters) could be vaporized? (Assume the density of wa
11Alexandr11 [23.1K]

Answer:

0.425 L  

Explanation:

Given the information from the question.  We know that the water heat evaporation is given by 2261 KJ/kg. Therefore, for each Kg of vapor, 2261 is required.

To calculate the amount of water evaporated by 960 KJ is as follows  

= (1/2260)*960 =0.425 Kg

In other words, 0.425 of water is evaporated by 960 KJ.  

To calculate the volume of water, we have mass and density. Therefore, Volume = Mass/Density = 425g/1g/ml = 0.425 L.

Therefore, water evaporated is 0.425 L
