What is the formula to find density when weight is 90N, Vol is 45ml, Mass is 9.0g
To find the density, you need to divide the mass of the object by its volume. The formula for density is:
Density = Mass / Volume
In this case, given that the weight is 90N, the volume is 45ml, and the mass is 9.0g, we need to convert the weight from Newtons to grams and the volume from milliliters to cubic centimeters because the mass is given in grams and the volume should be in the same unit for accurate results.
To convert the weight from Newtons to grams, we need to use the conversion factor that 1N is equal to 1000g:
Weight in grams = Weight in Newtons * Conversion factor
Weight in grams = 90N * 1000g/N
Weight in grams = 90000g
To convert the volume from milliliters (ml) to cubic centimeters (cm³), we use the fact that 1 ml is equal to 1 cm³:
Volume in cm³ = Volume in ml
Volume in cm³ = 45cm³
Now, we can substitute the mass and volume values into the density formula:
Density = Mass / Volume
Density = 9.0g / 45cm³
Density = 0.2 g/cm³
Therefore, the density of the object is 0.2 g/cm³.
