34g C * ( 1 mol / 12.0107 ) * ( 1 mol H2 / 1 mol C ) * ( <span>2.01588 g / 1 mol H2 ) = 5.70657164028741 g H2 = 5.7 g H2
Convert grams of C to moles of C using the given amount of grams and the molar mass ( 12.0107 g/mol ).
Gather the mole ratio from the coefficients in the balanced equation and multiply by the ratio.
Convert moles of H2 to grams of H2 </span> using the given amount of grams and the molar mass ( 2.01588 g/mol )<span>.

Answer:
A
Explanation:
1 lb = .453 kg...so...103 x .453 = 46.72 kg
you then multiply that by the force of gravity which is 9.8(m/s2)...so...
46.72 x 9.8 = 458 newtons(kg x m/s^2), which is the force.
pressure (in pascals) = Force(N) / Area (m2)
we need to convert 10cm2 to m2 which = .001m^2
458 / .001 = 458000 = 4.58 x 10^5 Pa
Answer:
D
Explanation:
Because the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes!!!
