Density is equal to the mass divided by the voulme.
So: 2.5 multiplied by 2.5 by 2.5.
Then: 295 divided by 16.625=18.88g/cm to the power 3
Answer:
4752 ft/min.
Explanation:
The following data were obtained from the question:
Speed (in mph) = 54 mph
1 mile = 5280 feet
1 hour = 60 minutes
Speed ( in ft/min) =?
Next, we shall convert 54 mph to ft/h. This can be obtained as follow:
1 mph = 5280 ft/h
Therefore,
54 mph = 54 mph × 5280 ft/h / 1 mph
54 mph = 285120 ft/h
Finally, we shall convert 285120 ft/h to ft/min. This can be obtained as follow:
1 ft/h = 1/60 ft/min
Therefore,
285120 ft/h = 285120 ft/h × 1/60 ft/min / 1 ft/h
285120 ft/h = 4752 ft/min
From the calculations made above, 54 mph is equivalent to 4752 ft/min.
Test tubes, spot and/or well plate will be used to combine substances in bottles and form a reaction is referred to a true statement.
<h3>What is a Chemical reaction?</h3>
This is the reaction which involves substances known as reactants combining new substances which are referred to as products. This is usually done in the laboratory and equipment and tools such as test tubes, thermometer etc are used.
Test tubes, spot and/or well plate are often used to combine substances in bottles and form a reaction which must be handled with care to ensure it doesn't spill.
This is therefore the reason why the option true was chosen as the most appropriate choice.

By 1.23 x 1024 you mean 10 to the power of 24 molecules? If so all you need to do is divide the number of molecules you have by Avagadros number, 6.022 x 10^23. This will give you the mols of water, or the mols of anything, since there is always 6.022 x 10^23 molecules in 1 mol of substance.
1.23x10^24 atoms/6.022x10^23 atom/mol = 2.04 mol H20
