Suppose that you have 10 g of ni and that the fraction of lattice sites that are vacant is 10–6. how many vacancies does your 10 g sample contain?

It equals just about 6,300 km per hour each day an week

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
