The steel would have a mass of 78g and the mercury would have a mass of 68g. So the Steel has greater mass.
Explained: This picture I also attached explains that whenever you have an equation dealing with density and volume alone, you will multiply the 2 together to get your answer for mass. And when your dealing with mass and rather volume or density you will divide the mass by whatever the volume or density is. For example if you need to find the density of an object that is 25g and 14ml you will write out this equation 25g/14ml= 1.78 g/ml. And if you need to find the mass of an object that is 27ml and 14g/ml you will write an equation like this 27mlX14g/ml= 378g. I hope this helps with your understanding.
A wind that blows at a constant speed parallel to curved isobars or contour lines is called a. gradient wind. Pressure changes. more rapidly in the vertical direction than in the horizontal. the pressure gradient force is directed from higher pressure toward lower pressure.

Answer:
Na + H₂O → NaOH + 1/2 H₂
Explanation:
When sodium reacts with water, it forms sodium hydroxide and molecular hydrogen. The unbalanced equation is:
Na + H₂O → NaOH + H₂
We have to balance this equation so it obeys the law of conservation of mass. We have 1 atom of Na on each side and 1 atom of O on each side, so these elements are balanced. However, we have 2 atoms of H on the left side and 3 atoms of H on the right side. The easiest way to balance the H without modifying the other elements is by making 1/2 the stoichiometric coefficient of H₂.
Na + H₂O → NaOH + 1/2 H₂
