If 12.5 grams of the original sample of cesium-137 remained after 90.69 years what was the mass of the original sample?
To find the original mass of the cesium-137 sample, you can use the exponential decay formula: final amount = initial amount * (1/2)^(time/half-life). With the information provided, you would have: 12.5 = initial amount * (1/2)^(90.69/30.1). Solving for the initial amount gives you approximately 40 grams.
Did you recover the same amount of copper you started with?
Yes, the amount of copper recovered through a chemical reaction or a purification process typically matches the initial amount that was present before the reaction or process began.
How much thorium in grams is there in 2 half lives?
To calculate the amount of thorium remaining after 2 half-lives, you use the formula: amount = initial amount * (1/2)^n, where n is the number of half-lives. If we assume the initial amount is 1 gram, after 2 half-lives, there would be 0.25 grams of thorium remaining.
How many grams remain after 20 years?
It depends on the substance and its rate of decay. The amount remaining can be calculated using the substance's half-life and the initial amount present.
What is initial moisture content?
Initial moisture content refers to the amount of water present in a material at the beginning of a process or experiment. It is usually expressed as a percentage of the weight of the water compared to the total weight of the material. Understanding the initial moisture content is important for various applications such as drying, storage, or food processing.

What is the amount of heat added to the gas during the initial compression process?
The amount of heat added to the gas during the initial compression process is known as the heat of compression.
What is initial cost?
An initial investment is the amount of money a company, business, franchise, partnership, or sole proprietorship starts out with to expand their company or business in the beginning.
How do you calculate the percentage of body fat loss?
To calculate the percentage of body fat loss, you can use the formula: (Initial body fat - Final body fat) / Initial body fat x 100. This formula compares the amount of body fat you started with to the amount you have now, and expresses the difference as a percentage of the initial amount.
What is the difference between initial margin and maintenance margin in trading?
The initial margin is the amount of money required to open a trading position, while the maintenance margin is the minimum amount needed to keep the position open.
What is the percentage growth from 279 to 257?
Percentage growth from 279 to 257 is Negative growth. Noting that you can tackle the problem anyway you want using 'subtraction' and the percentages (parts of 100)formula i.e % growth = ( (Final amount- Initial amount) / Initial Amount ) x 100 Therefore, Initial amount = 279, final amount is 257 257 - 279 = -22 (-22/ 279) x 100 = - 5.805 (3 decimal approx) - EK
How do you calculate the initial and final mass for a radioactive decay equation?
To calculate the initial and final mass in a radioactive decay equation, you would typically use the equation: final mass = initial mass * (1 - decay constant)^time. The initial mass is the quantity of the radioactive substance at the beginning, while the final mass is the amount after a specified amount of time has passed.
How can one calculate the amount of energy lost in a system?
To calculate the amount of energy lost in a system, you can use the formula: Energy lost Initial energy - Final energy. This means subtracting the final energy from the initial energy to find the difference, which represents the amount of energy lost.

How can I calculate the rate of return on my investment?
To calculate the rate of return on your investment, subtract the initial investment amount from the final value of the investment, then divide that result by the initial investment amount. Multiply the result by 100 to get the rate of return as a percentage.
How do you calculate the rate of return on an investment?
To calculate the rate of return on an investment, you subtract the initial investment amount from the final value of the investment, then divide that result by the initial investment amount. Multiply the result by 100 to get the percentage rate of return.
