Formula mass class 11
WebTherefore, NaCl is just the formula that is used to represent sodium chloride though it is not a molecule. In such compounds, the formula (i.e., NaCl) is used to calculate the formula mass instead of molecular mass. e.g. Formula mass of sodium chloride = atomic mass of sodium + atomic mass of chlorine. = 23.0 u + 35.5 u. Webτ = r x F = rF sinθ n. It is a vector quantity. If the nature of the force is to rotate the object clockwise, then torque is called negative and if rotate the object anticlockwise, then it is called positive. Its SI unit is ‘newton-metre’ and its dimension is [ML 2 T -2 ]. In rotational motion, torque, τ = Iα.
