Answer:
Explanation:
The density formula is
Rearrange the formula for mass, m, by multiplying both sides of the equation by v.
The mass can be found by multiplying density and volume.
The density of the sugar is 1.59 grams per milliliter. The volume is 237 milliliters.
Substitute the values into the formula.
Multiply. Note that the milliliters, or mL will cancel each other out.
The mass is 376.83 grams.
Answer: as the number of predators increases, more prey are captured. as a result the prey population starts to decrease.
Answer:
Natural gas
Explanation:
Natural gas is a gaseous fossil fuel produced from organic matter that is used to heat homes and cook food.
Natural gas is one of the most volatile part of hydrocarbons that exist together with fossil fuel.
- In a reservoir, natural gas is usually on top of the fossil fuel reserve.
- It can also be distilled from crude oil as they rises up on top of the column first due to their low boiling point
- The gas mixture is made up light hydrocarbons from methane to hexane.
Hello!
Ok so for this problem we use the ideal gas law of PV=nRT and I take it that the scientist needs to store 0.400 moles of gas and not miles.
So if we have
n=0.400mol
V=0.200L
T= 23degC= 273k+23c=296k
R=ideal gas constant= 0.0821 L*atm/mol*k
So now we rearrange equation for pressure(P)
P=nRT/V
P=((0.400mol)*(0.0821 L*atm/mol*k)*(296k))/(0.200L) = 48.6 atm of pressure
Hope this helps you understand the concept and how to solve yourself in the future!! Any questions, please feel free to ask!! Thank you kindly!!!
