n=PV/RT

convert:

740 torr to atm (1 atm=760 torr)

50 degree celsius to kelvin ( degree celsus +273= kelvin)

n=(0.9737 atm)(12.5L)÷(0.08206 L atm mol ⁻¹k⁻¹) (323 K)

n=0.4592 mols×22.4 L/1 mol.   (22.4 L STP= 1 mol)

=10.286 L at STP

it could be this

If the absolute temperature of a gas is 600 K, the temperature in degrees Celsius is A. 705°C. B. 327°C. C. 273°C. D. 873°C.
maksim [4K]

Answer:

Option B. 327°C

Explanation:

Absolute T° = T° in K

T° in K = T° in C + 273

T° in K - 273 = T° in C

600 K - 273 = 327°C

Given a 1.50 Liters of solution that contains 62.5 grams of magnesium oxide. What is the Molarity of that solution?
eimsori [14]
RMM of magnesium oxide=24+16=40
40g=1mol
therefore 62.5g will have =62.5/40=1.5625 moles
1.5 litres contain 1.5625 mols
therefore 1 litre =1*1.5625/1.5=1.042M

1. What type of person might have a high basal metabolic rate ?
kotegsom [21]
2.<span> It's important to know your blood type because it prevents the risk of you receiving an incompatible blood type at a time of need, such as during a blood transfusion or during surgery. If two different blood types are mixed, it may lead to a clumping of blood cells that can be potentially fatal.</span>

If you have 2 of the same substance and they are at the same temperature but have a different amount, what changes?
Lina20 [59]

Answer:

The heat energy stored within them changes

Explanation:

Heat energy is a function of the mass of a body, its specific heat capacity, and its temperature.

In this case, the bodies have the same specific heat capacity since they are made from the same material and the same temperature.

To get the quantity of heat stored in a body, we need to multiply all three parameters as shown below

Q = mC \Delta T

An increase in mass, through an increase in the amount of substance of a material present, will cause a corresponding increase in the heat energy stored within the material
