Answer:
Number of grams of mineral salt in one liter of water
.
Explanation:
Salinity :
It is the concentration of dissolved salts .
Salinity means the saltiness or the dissolved salt component in the water body . It is defined as mass (in gram) of the dissolved matter in the water bodies .
salts found in ocean water are :
Salts of chlorides, sulfates , sodium , magnesium, potassium and calcium
For example : world's oceans salinity is 3.5% parts per thousand (g/L) . It means 3.5 g of salt is present in 1 L of seawater .
Note : Sodium chloride is major salt found in ocean . But it is not the only salt present (other salts are also found) . So D can't be the answer
Answer:17.9 grams

Answer:
0.78 atm
Explanation:
Applying general gas equation
PV/T= P'V'/T'................ Equation 1
Where P = initial pressure, T = Initial temperature, V = Initial Volume, P' = Final pressure, V' = Final Volume, T' = Final Temperature.
make P' the subject of the equation
P' = PVT'/TV'.............. Equation 2
From the question,
Given: P = 1.00 atm, V = 5.20 L, T = 60°C = (273+60) = 333K, V' = 6.00 L, T' = 27°C = (27+273)K = 300 K
Substitute these values into equation 2
P' = (1×5.2×300)/(333×6)
P' = 1560/1998
P' = 0.78 atm.
