There are 6 states In the Mexican cession.
The Mexican Cession was the name granted the region of the modern day Southwestern US that Mexico gave up to the US. Before this, it was considered another part of Mexico.
The Mexican Cession.
The Mexican Cession included present-day California, Nevada, and Utah (that's three), along with portions of Arizona, New Mexico, Colorado and Wyoming. The "fourth" is probably Arizona, because it's made of land mainly from the Mexican Cession though it also includes a small portion from the later Gadsden Purchase. New Mexico is about half from the Mexican Cession, a small portion from the Gadsden Purchase, and the remainder from the Treaty of Guadalupe Hidalgo. Only small portions of Colorado and Wyoming were included in the Mexican Cession.
The most important consequence of the war for the United States was the Mexican Cession, in which the Mexican territories of Alta California and Santa Fé de Nuevo México were ceded to the United States under the terms of the Treaty of Guadalupe Hidalgo. In Mexico, the enormous loss of territory following the war encouraged its government to enact policies to colonize its northern territories as a hedge against further losses.

The Mexican Cession, which resulted from the U.S. victory in the Mexican-American War, added vast territories to the United States and reopened the contentious debate over the expansion of slavery. This raised questions about whether the new territories would be free or slave states, challenging the balance established by the Missouri Compromise of 1820. The compromise had maintained an equilibrium between free and slave states, but the influx of new land intensified regional divisions and led to renewed sectional tensions, ultimately contributing to the events leading up to the Civil War.
