After series of conversion from one unit to another, the number of gallons was found to be 12 litres
<h3>
Density, Mass and Volume</h3>
Given Data
- Density of Sulfuric acid = 1.84 g/cm3
- Mass of Sulfuric acid = 184.33 Pounds
Conversion from pounds to Gram
1 kg ---------2.204 lb
x kg ---------184.33 lb
x = 184.33/2.204
x = 83.634 kg
hence the mass in gram = 83.634*1000
mass in gram = 83634 g
Now let us find the volume
We know that density = mass/volume
volume = mass/density
volume = 83634/1.84
volume = 45453.26 cm^3
Convert cm^3 to litres
Volume in litres = 45453.26 /1000
Volume in litres = 45.45 Litres
Convert from Litres to Gallons
1 gallon = 3.79 L
x gallons = 45.45 L
x = 45.45/3.79
x gallons = 11.99 L
Approx = 12 Litres

The food has 23629.64 cal
<h3>Further explanation</h3>
Given
mass = 1000 g of water
temperature increases 23.65 * C
Required
The energy of the food
Solution
Heat absorbed by water :
Q = m . c . Δt
Q = 1000 g x 4.184 J/g°C x 23.65 °C
Q = 98951.6 J
1 Joules = 0.2388 Calories
98951.6 J = 23629.64 cal
Answer:
The answer to this question would be:
2. The exponents need to be the same so the leading numbers can be added or subtracted.
3. The result has the same number of decimal places as the least precise number.
The exponent is the 10^x that used in scientific notation. .When adding 12.3* 10^5 with 34.56 * 10^4, you need to make the exponent same first. In this case, it would become 12.3* 10^5 + 3.456 * 10^5= 15.756* 10^5
The decimal place could be rounded up to the least precise number. I'm not sure with the significant figures but it seems to use the biggest one.
