what is the pressure, in atmospheres, of 2.97 mol h2 gas if it has a volume of 73 liters when the temperature is 298 k? 0.50 atm
Triss [41]
P x V = n x R x T

P x 73 = 2.97 x 0.082 x 298

P x 73 = 72.57492

P = 72.57492 / 73

P = 1.0 atm

hope this helps!

makvit [3.9K]

Answer:

Explanation:

The correct measurement is .710 s which is equal to .71 s so second measurement that is 0.71 s is most accurate measurement .

B.  0.71s is the most accurate .

Precision depends upon measuring instrument . Measurement by highly precise instrument has greater precision .

The measurement of 0.75 ± 0.002s must have been taken from high precise instrument because it is capable of making measurement upto 3 decimal points .

Hence

C 0.75 ± 0.002s is most precise measurement .

Will you be my Magnesium, Silver, Nitrogen but "9.8m/s²" is silent? <br> Please help me here
zmey [24]
I don’t really understand but the symbols of these elements on the periodic table are

MgAgN

and 9.8 m/s^2 is the acceleration of gravity, commonly abbreviated as ‘g’

If you take out the ‘g’s from the periodic table equation(bc the question says 9.8m/s^2 is silent) it spells MAN

So the question could be “Will you be my man?”
