No. Of Bricks required for the wall N = color (purple) (80,000) Volume of the wall = L*B *H Given L = 4.9 m, B = 8 m, H = 2.4 m :. Volume of Wall V_w = 4.9 * 8 * 2.4 = color (green) (94.08 m^3) Volume of …

rho_"density"=5.0*g*mL^-1 By definition, "density" is the "mass" per unit "volume", and so we take the quotient.... rho_"density"= (200*g)/ (40*cm^3)=5.0*g*cm^-3-=5.0*g*mL^-1... Since we are in the …

1m^3 convert both units into metres: 1m = 100 cm -> 1m^2 = (100^2)cm^2 = 10^4 cm^2 10^12 cm^2 = (10^12)/ (10^4) m^2 = 10^8 m^2 2.0 * 10^12 cm^2 = 2.0 * 10^8 m^2 5 * 10^-9m = 5 * 10^-9 m to find …

The answer is 280 cm^3. A solution's percent concentration by mass is defined as the mass of the solute divided by the mass of the solution and multiplied by 100%. c = m_ (solute)/m_ (solution) * …

We can say that the weight of the dice decreased because of the buoyancy force of water on it. So,we know that, buoyancy force of water acting on a substance = It's weight in air - weight in water …

1.5 * 10^4"g mol"^(-1) Here's my interpretation of the problem The specific volume of a cylindrical virus particle is equal to 6.02 * 10^(-2)"cm"^3"g"^(-1). The radius of the particle is equal to 7Å and its …

The link immediately below the 30 cm point, and all the links below that one, rely on the link immediately above the 30 cm point for support. Therefore I will consider the lower portion as a separate object. …
