What solid has a melting point of 52 to 54 degree celsius and density 1.45?
without knowing the units of your density, I'm going to guess candle wax. I think the units are 0.87 plus or minus 0.02g/mL, so I would say Lauric acid which has a density of 0.88g/mL and a melting point of 43 degrees C.
How many atoms does Xe have?
Xe or Xenon has 1 atom in it , Xenon. Xenon has 54 electrons and 54 protons.
What volume is occupied of 2.4 moles of chlorine?
The volume that 2.4 moles of chlorine gas would occupy depends on the temperature and pressure of the gas, according to the ideal gas law (PV = nRT). At standard temperature and pressure (STP), which is 0°C and 1 atm pressure, 2.4 moles of chlorine gas would occupy approximately 53.75 liters.
How many electrons in Ba2?
Barium (Ba) has an atomic number of 56, which means it has 56 electrons in a neutral atom. The "2" you mentioned likely refers to the charge on the barium ion (Ba2+), which means it has lost two electrons, resulting in 54 electrons in the Ba2+ ion.
How many hydrogen atoms are in 7.20 mol of aluminum sulfide?
Stoichiometrically:2 Al :=: 3 H2SO4 :=: 1 Al2(SO4)3Molarity: 2:3:115 Al :=: 22.5 mole H2SO4 :=: 7.5 moles Al-sulfate
If aluminum has a density of 2.7 gcm3 what is the volume in cubic centimeters found in 54 grams of aluminum?
To find the volume of 54 grams of aluminum with a density of 2.7 g/cm3, divide the mass by the density: 54 grams / 2.7 g/cm3 = 20 cm3. Therefore, the volume of 54 grams of aluminum is 20 cubic centimeters.
A block of aluminum aluminum occupies a volume of 15.0 ml and weighs 40.5 g what is its density?
By definition: Density is equal to the mass divided by the volume. You have a volume of 20 ml and a mass of 54 g.
What is the density of an object have a mass of 54 and a volume of 300?
To calculate the density of an object, divide the mass (54) by the volume (300). The answer is about 5.
What is the volume of 0.054kg of water?
The volume of water can be calculated using its density, which is approximately 1000 kg/m³. By dividing the mass of water (0.054 kg) by its density, we can find the volume. Therefore, the volume of 0.054 kg of water is approximately 0.000054 m³ or 54 cm³.
a scientist has a sample of a substance with a volume of 50cm cubed and a mass of 135g. this is most likely a sample og which substance gold, pure water, aluminum or ocean water?
The **density** of a substance is defined as its mass per unit volume. We can calculate the density using the formula: [ \text{Density} (\rho) = \frac{\text{Mass} (m)}{\text{Volume} (V)} ] Given that the sample has a volume of **50 cm³** and a mass of **135 g**, let's determine the density: [ \rho = \frac{135 , \text{g}}{50 , \text{cm³}} ] The calculated density is approximately **2.7 g/cm³**[^10^]. Now let's compare this value to known densities: **Gold**: Gold has a density of *19.3 g/cm³*⁷. The sample's density is significantly lower. **Pure Water**: The density of pure water is approximately **1 g/cm³** at 4.0°C (39.2°F) . The sample's density is higher than water. **Aluminum**: Aluminum has a density of *2.7 g/cm³*[^10^]. The sample's density matches that of aluminum. **Ocean Water**: Ocean water contains dissolved salts, which increase its density. Seawater density typically ranges from *1.02 g/cm³ to 1.03 g/cm³*. The sample's density is higher than seawater. Based on the calculated density, the sample is most likely **aluminum**.
What is the density of a substance with a mass of 0.0450 kg and a volume of 26.4 mL?
The substance has a density of about 1.704 g/mL
What is the density of a substance that has a mass of 54 grams and a volume of 3centimeters to the 3rd power?
This is simple math. Density=Mass(grams)/Volume(milliliters) so since 3^3=27 then it works out to a simple D=54/27 aka 2. 2kg/L to be exact.
How do you convert l r a to ton?
To convert liters (l) to tons, you need to know the density of the substance in question. The conversion will depend on the specific substance's density. The formula for converting volume to mass is: mass = volume x density.
What is the volume of a tank that can hold 54 kilograms of methanol if the methonal has a density of 79g per cm squared?
Density is not mass per area, so this is invalid.
A block of wood 3.0cm on each side has a mass of 27g what is the density of this block?
A cube, with 3cm sides, has a volume of 3x3x3 = 27cc The weight is 27grammes. Density = weight / volume = 27g / 27cc = 1g/cc = 1000Kg/M3 A relative density of 1.0 (same as water)
How much does one cubic centimeter of aluminum weigh?
The density of aluminum is 2.7 gm/cc3 . So your 'cc' of aluminum contains 2.7 grams of mass. Assuming that it's located on or near the surface of the earth, it weights 0.026 newtons (0.952 ounce). (both rounded)
What is the volume of a deck of cards?
54 or 52
