A.
M = 0.125 M
V = 3.0 L
M=n/V(L) ⇒ n = 0.125 mol/L *3.0L = 0.375 mol
MM of K2SO4
K2 = 2* 39 = 78 g/mol
S= 32 g/mol
O4 = 4*16 = 64 g/mol
MM = 78g/mol + 32g/mol + 64g/mol =174 g/mol
mass = n*MM = 0.375 mol*174 g/mol = 65.25 g
b.
M= 0.015 M
V = 0.55L
n = 0.015 mol/L * 0.55L = 0.00825 mol
MM NaF
Na: 23g/mol
F: 19 g/mol
MM = 23g/mol + 19g/mol = 42g/mol
mass = n * MM = 0.00825 mol * 42g/mol = 0.3465 g
c.
n = M*V(L) = 0.350 mol/L * 0,700L = 0.245 mol
MM = 6*12 g/mol + 12*1g/mol + 6*16g/mol = 180 g/mol
mass = n*MM = 0.245 mol * 180g/mol = 44.1 g
A "A wind factor"
since an abiotic is a non-living condition or thing, The wind would be the most logical answer.
Hope this helped :D
We know that there are 100 cm in 1 m, so we need to add that into the conversion:
Or, in scientific notation:
In ridge push, the mantle wells upward because of the
convection and elevates the edges of spreading oceanic plates. Because these
plates are higher at the spreading center, they are forced downhill due to
<em>gravity</em> and eventually flatten out to the ocean floor.
