Moles x Mol mass = mass.
<span>Having looked it up, the mol.mass of U-238 is 238.03g/mol. </span>
<span>7.50 moles x 238.03g/mol. = 1,785.23g/mol</span>
The answer is t<span>he phosphoric acid in cola easily removes dirt and grime. The </span>"cola" type drinks is suitable to polish chrome surfaces. Cola contains a very diluted solution of phosphoric acid, which can remove rust, dirt, and grime from chrome surface.
On ground weight of plane will be measured as its actual weight which will be given as

now when plane is in air its weight is measured as combined effect of earth gravitational force and buoyancy force both
so weight in air will be given as

here since net effect due to air is opposite to the direction of weight so in air the plane weight will be measure less than its weight on ground.
so answer will be
A)more than a plane in the air
Answer:
yes for both.
Explanation:
according to Newton's first law an object in motion will stay in motion until acted on by an outside force and an object at rest will stay at rest until acted on by an outside force. this means that an object that is moving will stay moving in the direction that it's moving and at the same speed unless there's an outside force acting on it and it will keep in motion until there is an outside force acting on it.
