Hey there!
density = 2.67 g/cm³
mass = 1340 g
volume = ?
Therefore:
D = m / V
2.67 = 1340 / V
V = 1340 / 2.67
V = 501.87 cm³
So knowing the mass of C and H, C=12g and H=1g. We can have 3 C's (3*12=36) and 3 H's (3*1=3) so 36+3 is 39. Plus C3H3 has an empirical formula of CH since C3H3 can be simplified
Fossil fuels about into Earth ice age time
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
The process of fermentation in winemaking turns grape juice into an alcoholic beverage. During fermentation, yeasts transform sugars present in the juice into ethanol and carbon dioxide (as a by-product).
