What is the volume of 30 g of sodium?
The density of sodium at room temperature is 0.968g/cm3. Density = mass/volume. To find the volume of a substance from its density and mass, divide the mass by the density. V = M/D = 30g/0.968g/cm3 = 31cm3
What is molarity of 30g urea?
Urea has the formula (NH2)2CO, which equates to (14 + 2)2 +(12+16)= 32+28 = 60g Hence, 30g of urea is 0.5 mols.
The empirical formula of a compound is ch2oits vapour density is 45calculate its molecular formula?
To determine the molecular formula from the empirical formula and the vapor density, we first need to calculate the empirical formula mass. The empirical formula mass of CH2O is 12g (carbon) + 2g (hydrogen) + 16g (oxygen) = 30g/mol. Next, we compare the vapor density with the empirical formula mass to find the factor by which the empirical formula mass is multiplied to get the molecular mass. The factor is 1.5 (45 / 30 = 1.5). Finally, we multiply the subscripts in the empirical formula by this factor to get the molecular formula, which is C3H6O3.
How many 30g in 1kg?
There are 33.33 units of 30g in 1kg.
What is 30g in oz?
30 g = 1.06 oz.
What is the density of an object with a mass of 60g an a volume of 2cm3?
30g/cm3
What is the density if the mass is 30g amd the volume is 5ml?
The density would be 6 g/mL. To calculate density, divide the mass (30g) by the volume (5mL). Density = mass/volume = 30g / 5mL = 6 g/mL.
Calculate the density of a sample of gas with a mass of 30g and a volume of 7500cm3?
density= mass/volume 30g/7500cm3=.004g/cm3
What is the density of a 30g cube with length of 5cm?
Density = Mass/Volume Volume of cube=5cmx5cmx5cm=125cm3 So 30g/125cm3=0.24g/cm3
What the density of a mango if its mass is 30g?
Density depends on 2 things, mass and volume. If you don't know the volume you cannot calculate the density.
If the volume of a mineral is 15ml and the mass is 30g what is the density?
The density of the mineral would be 2 g/ml (density = mass/volume).
How is the density formula rearranged to solve for v?
density = mass/volume volume = mass/density mass = volume*density Here are some numbers from a recent chem experiment that prove this. 4.360g/mL = 30g/6.88mL 6.88mL = 30g/4.360g/mL 30g = 6.88mL*4.360g/mL
What is the density of an object with the mass of 30 grams and the volume of 6 cm?
To find the density of an object, it would be D=m/v.So the density would be: 7.3099415204678362573099415204678 kg/L.But in this, there are also significant figures, and so in 6.25, there are 3. Therefore, the answer cannot be more precise than the given equation.So it would round to 7.30.Density = 7.30 kg/L.
Why does the object with same volume and different mass has a greater density?
an object is more dense if there is more weight in the same area, its because of the amount of particles and the weight of the particles. eg, 1cm cubed of gold would weigh alot more than 1cm cubed polystyrene, so gold is more dense
How do you find mass if density isn't given?
You don't need density to find mass. In a lot of question you need to find density with the given mass and volume. But to find density you would use a triple beam balance. To find volume you would either measure the length, width and height or you could fill a beaker up with water lets say 50g and then put the object in the beaker and lets say it raised up to 80g all you have to do is subtract 80g-50g=30g. To find density with volume and mass you divide mass------volume and get density.
What is the volume of 30 g of sodium?
The density of sodium at room temperature is 0.968g/cm3. Density = mass/volume. To find the volume of a substance from its density and mass, divide the mass by the density. V = M/D = 30g/0.968g/cm3 = 31cm3
What is plastic block of dimensions 2.0cm 3.0cm 4.0cm has a mass of 30 gram .what is its density?
Density is given by the formula: density = mass/volume. The volume of the block is calculated by V = lwh where l = 2.0cm, w = 3.0cm, and h = 4.0cm. Substituting these values in, V = 2.0cm * 3.0cm * 4.0cm = 24.0 cm³. Thus, density = 30g / 24.0 cm³ = 1.25 g/cm³.
