Answer: The given statement is False.
According to alternative hypothesis, observed difference exists between research variables, which does not occur by chance.
Whereas, a non directional alternative hypothesis has no definite directions of the difference but a certain difference does exist.
Thus, the given statement is False.
Molarity is a way of expressing concentration that is equal to the ratio of the moles of the solute to the liters of solution. The amount of substance in moles can be calculated through,
moles = (molarity) x (volume in liters)
Substituting the values,
moles = (0.135 M) x (5.0 L) = 0.675 moles
Multiply this value with the molar mass of sodium ion,
mass = (0.675 moles) x (23 g/ mole) = 15.525 grams
Therefore, the mass of sodium ion in the blood is 15.525 grams.
Although it's true that MgO is only very slightly soluble in water, you can consider the mixture a conventional solution for the purposes of this question. The % mass is the mass of MgO divided by the mass of the entire solution:
45.8 / (45.8 + 205) * 100 = <span>18.3%</span>
If the pressure increases to 300 KPa and the volume remain constant the temperature will be
900K
it is calculated using the gays lussac law formula that is P1/T1=P2/T2
P1= 100Kpa
p2=300Kpa
T1=300k
T2=?
by making T2 the subject of the formula T2 =P2T1/P1
=300KPa x300 k/100 kpa = 900 K
