M=70.0 g
p=0.70 g/mL

v=m/p

v=70.0/0.70=100.00 mL

Calculate the amount of nacl needed to prepare 50 ml of 0.9% nacl solution and 20% nacl solution
Westkost [7]
Your answer would be, 
Formula: Molarity (M) = Number of moles of solute/Solutions volume Liters

0.009(50) = .45 gm dissolved in 50 ml H2o
= 0.20(50) = 10 gm





Hope that helps!!!

A scientist fills a large, tightly sealed balloon with 75,000 mL of helium at STP.
pav-90 [236]

Considering the definition of STP conditions, 3.35 moles of helium are contained within the balloon.

<h3>Definition of STP condition</h3>

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

<h3>Amount of moles of helium within the balloon</h3>

In this case, you know that scientist fills a large, tightly sealed balloon with 75,000 mL of helium at STP.

So, you can apply the following rule of three: if by definition of STP conditions 22.4 liters are occupied by 1 mole of helium, 75 L (75 L= 75000 mL, being 1 L= 1000 L) are occupied by how many moles of helium?

amount of moles of helium=\frac{75 Lx1 mole}{22.4 L}

<u><em>amount of moles of helium= 3.35 moles</em></u>

Finally, 3.35 moles of helium are contained within the balloon.

How is geothermal produced
soldier1979 [14.2K]
The steam rotates a turbine that activates a generator, which produces electricity. Many power plants still use fossil fuels to boil water for steam. Geothermal power plants, however, use steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface.

According to Pascal's principle, how does pressure from a hand squeezing a ketchup bottle move throughout the ketchup?
Pepsi [2]

- According to Pascal’s principle, for a certain fluid in a totally enclosed system, a change in pressure at a given point in the fluid is transferred to all points in the fluid, as well as to the enclosing walls.

- This is illustrated by the fact that the pressure inside an enclosed system is the same according to the relation [ pressure = force/area ]. Therefore, the change in pressure resulting from squeezing a ketchup bottle will be transferred equally to all parts of that bottle as well as its internal content.

- That’s how hydraulic machines, such as garbage trucks and hydraulic lifts function..
