I am assuming you mean the density is 4.0 g/ cm3 and the displaced H20 is 3.0 cm3 (3 mls when converted to cm3). Look at the units that should tell you how to solve the problem. Your answer must in g (mass), thus you take 4.0 g/cm3 times 3.0 cm3. Units are treated like numbers, for example 3 times 1/3 equals 1 - both 3's cancel leaving only 1 time 1 which equals 1. In this case you have 4 g/cm3 times 3.0 cm3, cm3's cancel leaving only g as your unit at the end. The rest is for you to solve! Enjoy your problem.

What is the proper way to smell something in a science lab?
To properly smell something in a science lab, hold the container a few inches away from your nose and gently waft the scent towards you with your hand. Do not directly inhale the fumes as they may be harmful. Always use a fume hood if working with strong odors or toxic chemicals.
The car lift in a gas station operates with an aire pressure of 2000 kPa The piston of the car lift has a diameter of 30 cm What is the mass of the largest car that the lift can raise?
To calculate the mass of the largest car the lift can raise, you need to consider the force exerted by the pressure on the piston, which is given by the formula F = P * A, where A is the area of the piston. First, calculate the area of the piston using the formula A = π * r^2, where r is the radius of the piston. Then, calculate the force F exerted on the piston. Finally, you can convert the force into mass using the formula F = m * g, where m is the mass of the car and g is the acceleration due to gravity (approximately 9.81 m/s^2).
What is the proper way to smell a chemical in the lab?
1. Put your nose on the same height as the source of the smell and about 10-30cm away 2. make some wind with your left arm, so that the fumes go toward your nose 3. inhale
What is stronger beta radiation or gamma radiation?
Gamma radiation is stronger than beta radiation. Gamma rays are a type of electromagnetic radiation with high energy and penetration power, while beta particles are high-energy electrons or positrons. Gamma rays can penetrate deeper into materials and are more difficult to shield against compared to beta radiation.
A 35.0 mm x 75.0 mm piece of aluminum density 2.70 gcm3 is 0.80 mm thick What is the mass in grams of the metal?
Since the density is quoted in g cm^(3), then you first convert the 'mm' to 'cm' by dividing by '10' There 10 mm = 1 cm Hence 35,0 mm = 3.5 cm 75 mm = 7.5 cm 0.80 mm = 0.08 cm Multiply together to obtain the volume in 'cm^(3) Hence 3.5 cm X 7.5 cm X 0.08 cm = 2.1cm^(3) Now remember Density = mass / volume d = m(g) / v(cm^(3) Algebraically rearrange mass(g) = d X v Hence mass = 2.7 g cm^(-3) X 2.1 cm^(3) mass = 5.67 g
