Answer:
Explanation:
a ) 15( ft)³ = 15 ( 12 inch )³ = 15 x 12 x 12 x 12 (inch)³ = 25920 (inch)³
=25920( 2.54 cm)³ = 25920 x 2.54 x 2.54 x 2.54 cm³ =424752.7 cc
424752.7/1000 litre = 424.75 liter
424.75 liters cost 1.30 dollars
1 liter costs 1.3/424.75 = 3.06 x 10⁻³ dollars.
So rate
= 3.06 x 10⁻³ dollars/liter
b ) one liter of water takes 0.304 ft³ of gas
2.1 liter will take 0.304 x 2.1 = 0.6384 ft³ of gas
cost = 1.3 x .6384 / 15 = 0.055328 dollar = 55.33 x 10⁻³ dollar.
Co2 will dissolve in water if water is saturated with Co2 first then it will absorb some of CO2 it appear as less is absorb that was actually the case . this would make it appear as present of CACO3 is in original sample is lower than it will be too low
Answer:
50
Explanation:
so you'll have to apply Newton's 2nd law which is F=ma and then substitute the values that you already have in the question as in, the force is 200 and you'll have to find the acceleration by working it out which is 4m/s² and then find the mass by dividing 200 by 4 so the actual mass is 50kg ✌️❤️
Find the molar mass of the compound, then get the unit cancel out until u reach "g"
